An hour later, Eiji and Kei came out of the cake shop holding hands. Their handsome and beautiful appearance made them look harmonious in the eyes of everyone except Shirogane.
Shirogane was now hiding behind a tree on the side of the road.
Although he was so angry and jealous that he wanted to tear someone apart, he was still quite rational.
At least until he heard Eiji say, "Kei, do you have any other plans after this?"
He called out to her more intimately than before.
Kei was still not used to it, she was a little embarrassed but shook her head and hesitantly answered. "No, Eiji... I don't have any other plans."
She didn't call him Senpai anymore.
Eiji smiled, "Then, how about we continue our date? I remember not far from here there is an aquarium with a small movie theater inside. We can book a private or VIP room underwater to watch a movie together while watching the fishes swim."
Kei's eyes lit up, she had never been to an aquarium because the average admission price was quite expensive.
And with her family's financial condition, she always refrained from buying things that were not very useful or just to entertain herself.
But now? She's Eiji's girlfriend, she can't refuse to have fun with him, right?
Kei thought rather tsundere-like.
"Sounds like fun. I agree, let's go there."
"Good." Eiji said before tugging on the silver-haired beauty's hand.
Their fingers intertwined.
Feeling Eiji's hand that was bigger than her enveloping her small hand, Kei felt happy.
Still, when they were about to walk— Shirogane's anger-filled voice came from behind.
"Stop!"
Eiji was not surprised, the protagonist finally could not resist coming out of his hiding place.
Kei frowned, she turned around with a cold expression. Just like Eiji, she was also not surprised and pretended to be new to her older brother's existence.
"Why are you here?"
She asked harshly.
Shirogane was saddened that Kei seemed to be starting to not think of him as her older brother.
This was all Eiji's fault!
He glared at the silver-haired boy who looked good together with Kei with hatred and jealousy in his eyes. Especially when he saw their hands still connected to each other.
He wanted to separate them!
"Why I'm here is not important. Kei-chan, what's more important is that you shouldn't be alone with Eiji in a room. He wants to take you to watch a movie in a private room, he must want to do something bad to you!"
"You're a pretty girl, you should be more vigilant, Kei-chan!"
Shirogane admonished his younger sister.
Hearing Eiji wanted to take the girl to a room where there were only the two of them, she could imagine what might happen.
Not content with just stealing Kei's first kiss, Eiji also wanted her virginity.
Shirogane's head was filled with green, he was worried that if he didn't stop them soon, he would really lose his younger sister!
"Let me guess, you must have followed me secretly from home. You're disgusting." Kei made an unbelievably disgusted expression.
"Kei-chan, that's..." Shirogane panicked.
But Kei didn't let the blonde boy finish his words.
"And I refused your request! Who do you think you are? You 'may' be my older brother but Eiji is my boyfriend! Even if he does those things to me, I won't refuse."
Eiji whistled in his heart.
Worthy of being his woman, Kei knew how to hurt the protagonist's heart.
He enjoyed seeing the shock, sadness and various negative emotions on Shirogane's face.
Shirogane clearly didn't expect Kei to be so humble to Eiji. Jealousy welled up in his heart, he didn't even realize the girl might have found out he wasn't her older brother.
"Why, why are you so humble to a bastard like him?! Kei-chan, you, you must have been tricked by him!"
Shirogane could not believe his younger sister whom he even knew from the original work would give up her body that easily to a man.
And that man was Eiji who made him almost faint in anger.
Did Kei really like that bastard?
No way! No way!
Kei must have been forced by him!
Shirogane was still trying to deceive himself like the other protagonists in similar situations.
Hearing Shirogane slander her boyfriend, Kei was so angry that her slender shoulders could be seen shaking.
Their argument attracted the attention of people passing by. One of them was a pink-haired girl with a black ribbon in the middle of her bangs.
"It's so crowded, eh... Isn't that Kei-chan? And next to her is... Eiji?!"
It was Chika Fujiwara.
On a sunny Sunday, she was shopping with her younger sister. However, she didn't expect to see a love drama.
She also recognized Shirogane because he was the new student council president at her school.
Still, isn't Kei his younger sister?
Chika's brain working in a different way than normal people, she widened her eyes and covered her mouth with one of her hands.
'Could it be a love triangle and forbidden?! Seeing his younger sister dating Eiji, a siscon like Shirogane-san can't stand it.'
If Eiji heard what Chika was thinking, he would be a little surprised.
Because it's true!
Shirogane transmigrator was a disgusting siscon!
"Nee-chan, put Kei aside. Is Eiji that very handsome boy? Do you know him?"
Standing beside Chika, a cute girl who also had pink hair but was cut short with double pigtails asked excitedly.
Her name was Moeha Fujiwara.
Among her sisters, she was the youngest and was currently a third-year student in the junior high division of Shuichiin Academy.
"Ah, yes. I know Eiji." Chika answered honestly.
But she did not understand why her younger sister was so excited.
Moeha smiled and said, "After this, let's greet Kei and introduce me to Eiji-san."
"....."
Chika was worried, there was no way Moeha was interested in Eiji, right?
She knew Eiji was very handsome but...
Moeha, are you a nymphomaniac?!
...
Eiji was aware of Chika and Moeha's existence because he heard them talking about him.
However, his attention was currently only on Shirogane.
"Kei, don't worry. Let me talk to your older brother."
He let go of Kei's hand and squeezed her soft shoulder.
Kei felt an electric shock that made her body slightly hot, her white cheeks could not help but blush and she said, "Um."
This was the first time Shirogane had seen his younger sister speak softly to someone.
But that someone was not him, it was Eiji.
{Damn it! Quickly get your dirty hands off my sister, Eiji! Had I not realized the physical difference between us, I would have beaten you up and torn you apart by now!}
The heroines fell silent.
Protagonist, why are you only saying that in your heart?
Aren't you just...
[Shirogane is too cowardly, he only dared to scold me that hard in his heart. Honestly, I'm disappointed.]
They didn't understand why Eiji was disappointed but what he said was true.
Kei nodded in her heart, she continued to look at Shirogane with disdain.
Eiji removed his hand from Kei's shoulder and walked up to the boy who was supposed to be his future brother-in-law.
There was a playful smile on his face, "Shirogane, we meet again. But now, Kei and I are dating. You are my future brother-in-law, I hope we get along well."
"I don't have a future brother-in-law like you! Eiji, stop being hypocritical, you're not a good person, you deliberately targeted me many times and now you're doing it again by tricking Kei, right?!"
Shirogane was intimidated by Eiji's muscular figure and taller than him. However, he ventured to raise his head and glared fiercely at him.
Eiji looked down at Shirogane and innocently said, "How did I trick Kei? We like each other and just decided to date."
"Of course you didn't tell her that you're engaged to Kaguya and have a romantic relationship with Hayasaka. Eiji, you are a playboy, you must still have more girls who are in a romantic relationship with you."
"Kei-chan doesn't know this... Wait, you said you two just started dating?!"
Shirogane suddenly realized something.
Eiji and Kei had just started dating but they had kissed passionately before.
Isn't that too soon?
And Kei didn't refuse?
Damn it! Damn! First was Hayasaka, she didn't refuse to go to the love hotel with Eiji. Then Kaguya, she also didn't refuse to kiss Eiji in front of many students even though they were at school!
Now he saw his own younger sister, Kei casually having a French kiss with Eiji less than an hour after they started dating.
Feelings of pain like an NTR victim and jealousy continued to bombard Shirogane's heart.
He had transmigrated into a protagonist.
But why? Why does he now feel that Eiji is the protagonist and he is a minor character being trampled on?
From the viewpoint of the spectators including Chika and Moeha, Shirogane's face was very green as if he could turn into the Hulk at any time.
Many of them were amused and couldn't help but laugh.
"Hmm..." Eiji held his chin and looked back to see Kei, "I'm not a playboy, but I do intend to do polygamy in the future. Even so, I haven't told Kei about my other potential wives yet."
Shirogane's eyes lit up, he also glanced at younger sister while pointing at Eiji. "Did you hear that, Kei-chan? Eiji, lying, he's definitely a playboy."
He then sneered and said, "This country doesn't support polygamy, but even if he does, are you willing to share a man with another woman? Kei-chan, don't lower yourself just for him, you can have other better man."
{For example, your older brother, isn't he very nice? He's not as handsome as Eiji, but he's very loyal! Kei-chan, you can only marry me!}
[I'm sure if Kaguya and Hayasaka aren't in love with me, Shirogane isn't as loyal as he says. Even now as long as there are pretty girls who confess to him, I doubt he will refuse to date her. Men understand men, and I know the transmigrator who has stolen Shirogane's body also has the desire to create a harem like me.]
Heard the inner voices of Shirogane and Eiji.
Even without their biases and feelings towards Eiji, the heroines felt what he said was more believable than Shirogane's words.
Not only that, Kei had also long known that Eiji had a harem from his inner voice. She often felt jealous when she heard him talking about other women in his heart.
However, Kei realized she could not be the only one for Eiji.
Eiji was too extraordinary that many beautiful women like Kaguya-senpai and others were willing to join his harem.
Even those women didn't mind sharing a man.
What about her?
"I don't mind, I know I won't be Eiji's only girlfriend or future wife. Shirogane, no matter what you say, I still like him."
Kei said that.
The spectators including Chika and Moeha were stunned.
The corners of Eiji's lips lifted higher. It was not for nothing that he always let the women he wooed know that he had a harem from his inner voice.
It was nothing but a precaution so that in a situation like this, they would not be surprised and would already be mentally prepared to slap the protagonists.
(As expected of a villain boss behind the scenes.)
'Miss System, thank you for the compliment.'
[....]
Miss System wanted to say she was mocking her host, but was too lazy.
Shirogane staggered back, he looked at Kei in disbelief. "Kei-chan, you... What drug did Eiji give you?!"
Kei rolled her eyes, "What nonsense are you saying? Go away and don't disturb my date with Eiji."
Her words were like arrows piercing Shirogane's heart.
Eiji used this opportunity to rub salt into Shirogane's wounds, he lowered his head and whispered not far from his ear.
"You heard what Kei said, Shirogane? By the way, I've been wanting to tell you for a long time... Hayasaka and Kaguya are so moist, they also have great cooperation in bed."
In other words, he had a lot of fun with the two girls when having a threesome with them.
The nightmare Shirogane had a few days ago was actually real.
"!!!" Shirogane realized that, blood dripping at the corner of his mouth and his nails digging into his palm.
The scenes in the nightmare were real?
Excruciating pain pierced his heart sharply.
He realized that he now had three green hats on top of his head. His vision gradually darkened and he fainted.
But at that moment, Eiji and Kei were already walking away from him.
"Hiss! He fainted!"
"That's why you shouldn't be a siscon. That kind of thing won't go well in the real world."
"What about the harem? That really handsome boy seems to have it and his girlfriend doesn't mind sharing him with other women!"
"Damn, I'm so jealous!"
"Ehem. Poor boy. Who wants to take him to the hospital?"
One of the people crowding around Shirogane asked. But everyone he was staring at averted their gazes.
Good people.
In the end, he reluctantly called for an ambulance.
Still, just like Kazuya, many people also took pictures of Shirogane and posted his pathetic state on their respective social media accounts.
It didn't take long for Shirogane's reputation as the student council president of Shuichiin Academy to be affected because of that.
...
On the other side, when Eiji and Kei were about to enter the aquarium.
Chika and Moeha finally greeted the two of them.
"Yo Kei-chan, Eiji. What a coincidence that we met, how about we enter together?"
"Chika?" Eiji pretended to be surprised and said, "Sure, I don't mind. Do you and Kei know each other?"
"Hehe, yes! Kei-chan is a junior at my school and a friend of my younger sister. She's even played at my house many times."
Chika laughed merrily and jumped up and down so much that her large breasts jiggled, she was truly an extrovert who in the original work often gave Kaguya a headache and envied her figure.
Still, even though she looked stupid, she had good enough acting skills to pretend that they had just seen her and Kei.
And the girl beside her, Eiji knew she was her younger sister. Moeha was the same age as Kei, but her body shape almost caught up with her two older sisters.
The Fujiwara family's genes are very good.
They were fit to be the mother of his children!
"Is it true, Kei?" Eiji asked calmly to his new girlfriend.
Kei was surprised to meet Chika and her classmate, Moeha. Still, she pouted a little as they interrupted her date with Eiji.
"Yes, we know each other and have a good relationship."
Eiji nodded, he then turned his gaze to Moeha. When their gazes met, she continued to look at him dazedly.
Interesting, this girl doesn't seem like it would be difficult to conquer, Eiji thought.
"You must be Chika's younger sister. Just like your older sister, you're very cute."
"...!" Not only Moeha, but Chika also blushed when she heard his words.
Kei's lips twitched, was Eiji teasing the other girls in front of her?
She was a little uncomfortable and jealous, but considering the harem Eiji had, she knew sooner or later she would have to get used to this.
"Y-Yes, this is my younger sister. Her name is—" Chika stammered but before she finished her words.
Her younger sister interrupted her, "Hello Senpai, I'm Moeha Fujiwara. I'm a third year junior high school student like Kei."
Moeha introduced herself while patting her chest which was only slightly smaller than Chika.
Her gesture looked flirtatious which annoyed Kei.
She could see that Moeha was seducing her boyfriend with her body.
Damn it, are you a bitch?!
"I'm Eiji Seiya, I'm the same age as Chika. Nice to meet you, Moeha-chan. Well, let's go in. I'll also treat you two to a movie with us."
Eiji's expression did not change, he was still smiling and did not look embarrassed or excited when Moeha seduced him.
It made him look even more like a male god.
Moeha, who was a face controller, started to like him more in just a short time.
She envied Kei for being able to be one of Eiji's girlfriends.
Hearing what Eiji said, Moeha and Chika didn't refuse, they thanked him and showed how excited they were.
Soon, Eiji took a walk in the aquarium and watched a movie with the three beautiful girls. In the process, Moeha often hugged one of his arms and out of jealousy, Kei glared at her while hugging Eiji's other arm.
Even so, Kei didn't really stop Moeha.
Moeha felt Kei was such a good sister, she seemed to give the green light to seduce her boyfriend and share with her.
Only Chika felt like she was a light bulb. She could hardly enjoy looking at the fishes and the movie they were watching because at that time, her attention was often distracted by her younger sister who was shamelessly seducing Eiji.
Gosh, Moeha!
Even after you know Eiji has a harem and is Kaguya's fiancee, you're still crazy about him?
You really are a nymphomaniac!
Still, it would be a lie if Chika said she wasn't jealous of seeing those three making out in front of her.

Author Note
Thank you to those who have prayed for my recovery and read my book so far.
To be honest, I might have been unwell a lot in the past two months because I was trying to fulfill the requests from my webnovel and patreon subscribers.
Of course, not all of them but I just tried to add some things that I think are still in line with my mind. But still, the rest like changing the MC's personality to not be narcissistic or something like that was something I had a hard time doing.
The repitive stuff is also starting to tire me out as I write daily chapters. Within the limited time, I also have to think about the plot etc. After coming this far, even I'm having trouble coming up with ideas myself.
I'm not like those writers who use AI to make their monologues and even dialogues look different and new in every chapter. If I do that, I feel like my feelings in the words I write in each chapter will be lost.
At this point, I also often feel like I'm writing things I don't like just to fulfill a request. In the end? Some people were still unsatisfied and I felt very tired.
