With clues in hand, Nobi Hiroshi immediately suggested, "Then let's go to the Future World now and investigate that Museum!"
As his voice faded, Doraemon, who was scratching his face with his hind leg, stopped his action, lowered his head regretfully, and said with some frustration, "The Secret Gadget Museum requires an invitation. Without a reservation, ordinary people can't get in."
"Oh~"
"How troublesome. It's just a bell. Doraemon, why don't you just get another one?"
Nobita waved his hand indifferently, feeling that it was just a trivial matter.
For an ordinary bell, first a notice, then an invitation, he really didn't find it troublesome.
"How can that be? This bell is especially important to me!"
"Nobita, have you forgotten…?"
Looking at the shaking head of Nobi Nobita, Doraemon was furious, his high-pitched voice growing weaker and weaker, finally becoming like a monologue.
"Especially important, why?"
Nobita scratched his cheek and asked, puzzled.
"That… you don't need to know that. Just know that it's very precious to him!"
Doraemon turned his face, which held a hint of shyness, and evasively refused to answer.
What kind of secret was hidden within, no one knew, but Nobi Hiroshi felt that Doraemon had been acting unusually ever since he lost the bell.
His emotions were as extreme as a split personality.
"It's very important, huh? Since you say so, we can't just stand by."
"But, do you have any way to get into that Secret Gadget Museum?"
Nobi Nobita said seriously. Although he was a bit slow-witted, he deeply understood empathy for important things.
"I remember Doraemi said she had a Museum invitation ticket."
"I've been a bit busy recently, I almost forgot!"
A flash of inspiration, Doraemon suddenly remembered his younger sister and took out a future phone from his four-dimensional pocket to call Doraemi.
"Hello, hello, is that my dear sister?"
"Brother needs that Museum invitation ticket now. Please come over quickly~"
His voice was sickeningly sweet, making Nobi Hiroshi's goosebumps rise.
Glancing at the humble look of him with his face pressed against the phone, Doraemon was definitely a sis-con!
...
...
Resting cross-legged, the three sat quietly in the room waiting. After about ten minutes, the drawer of Nobita's desk suddenly popped open, and a yellow figure bounced out, landing nimbly on the floor.
"Brother, I'm here!"
Standing on the tatami, Doraemi looked at her brother, a voice as sweet as cotton candy coming from her throat.
Her round and cute body was carved from the same mold as Doraemon, and her delicate features were embedded with round, moist big eyes.
Her yellow body also had no cat ears, but it was probably replaced by the large pink bow tied to the back of the girl's head.
Even without cat ears, it didn't hinder Doraemi's appearance.
As a robot, she had a bit of a tsundere personality like a young girl. After greeting her familiar brother and Nobita, she looked at the unfamiliar Nobi Hiroshi and proactively introduced herself.
And the master of making friends, Nobi Hiroshi, was never lacking in politeness. He extended his hand to shake, purely naturally friendly.
"It's nice to meet you, Hiroshi. I hope my clumsy brother hasn't caused you any trouble?"
Doraemi smiled gently. The Doraemon next to her looked melancholic upon hearing this; his past clumsy nature could not be erased from his sister's heart.
The person and the cat chatted happily after getting acquainted. Doraemon took the opportunity to get strawberry cake from the kitchen as a bridge to support their sibling relationship.
Having good judgment was very important, especially when asking for a favor, even between siblings, a small bribe was indispensable.
"Brother, there's no need to go to all that trouble. I'll buy you a new bell at the Future Department Store."
Not long after, Doraemi understood the situation and said with a happy face while eating the strawberry cake.
She was deeply surprised that DX stole the bell, surprised that her brother cared so much about such a small matter.
"How… how can even you say that?"
"Doraemi, brother tells you, besides that bell, I absolutely don't want any other bells!"
Doraemon lay on the ground, throwing a tantrum like a child.
Doraemi looked at Doraemon, the plastic fork in her hand unknowingly dropping. She sighed helplessly and said, "It seems that bell is really important to brother…"
"But I went through a lot of trouble to get this Museum invitation ticket, so I can't just give it to you for free."
Doraemi smiled slyly, took out the invitation from her four-dimensional pocket, her almond eyes showing a mischievous glint of extortion as she gently shook the card in her hand.
"Alright, I understand."
"Doraemi, next time brother will send you ten pineapple buns!"
Doraemon smiled awkwardly, offering a bargaining chip between siblings.
Unfortunately, he greatly underestimated the girl's greed for pineapple buns.
"Beep beep, I want twenty!"
Doraemi said lightly.
"Twenty… twenty!"
"…Alright, I promise."
Glancing at the smug Doraemi, Doraemon gritted his teeth and spoke after a long deliberation.
Twenty pineapple buns? It's fine, I'll just eat a few less dorayaki next month.
"Hehe, here you go, brother. This ticket allows six people to enter the Museum."
"There's a special sale on pineapple buns today, so I won't be accompanying you. Bye-bye!"
Doraemi handed the invitation ticket to Doraemon, wiped the cream from the corner of her mouth, and returned to the Future World in her rose-shaped time machine.
"It's such a shame Doraemi can't go. So, Doraemon, let's go find Gian, Xiao Fu, and Shizuka, and ask them if they want to come along."
Nobita got up to clear the plate after Doraemi finished the cake, saying excitedly.
"Alright, meow~"
Doraemon took out the anywhere door and replied, but he became abnormal again, starting to rub against Nobi Hiroshi's pants like a cat, meowing incessantly.
"Is… is Doraemon sick? Should we call Doraemi back?"
Nobita frowned and said.
"No need, I think it has something to do with the bell. If we don't get the bell back, Doraemon's illness won't get better."
Pushing away Doraemon's constantly rubbing head, Nobi Hiroshi pinched his chin and guessed.
"That makes sense, but what should we do now?"
"Uh, I think we can find some substitutes, like something yellow and round."
Hiroshi said while rummaging through the drawer, it wasn't that simple to find a substitute.
Walking to the kitchen, Nobi Hiroshi found a lemon in the refrigerator and, without a word, hung it around Doraemon's neck. It surprisingly fit well.
"Pfft~ Hahahaha~"
Nobi Nobita looked at the lemon on the collar and couldn't help but laugh out loud, while covering his face to suppress his expression, avoiding excessive facial contortions.
"Nobita, what are you laughing at?"
The normal Doraemon asked suspiciously. Seeing the other party pointing at his neck, he quickly walked to the mirror to look.
I'm eating a lemon!
"This is too embarrassing! I must get my bell back!!!"
Yelling to the sky, Doraemon looked at the cat in the mirror with a look of despair, almost laughing at himself.
Wearing a lemon around his neck made him look incredibly comical, but it was also an impeccable choice.
He wasn't without memory of his previous cat-like behavior. If he didn't wear this lemon, the absurd things that would happen later would only get stranger.
After some deliberation, he could only condescend to compromise.
"Hiroshi, what kind of outfit is that? Are you role-playing?"
"But this all-pink outfit, I'm starting to doubt your aesthetic sense."
Eyes met. Gian, who was called by Nobita on the phone, stood in the yard, powerlessly complaining about Nobi Hiroshi at the entrance.
"Exactly! So funny! Only girls would wear that color!"
Xiao Fu next to him quickly echoed, instinctively mocking, while a hint of envy flashed in his eyes.
"No way! I think you look great, Hiroshi! Who says boys can't wear that color! Xiao Fu, your outlook is too narrow."
Tian Mei, with golden light in her beautiful eyes, loudly defended him, standing in front of Nobi Hiroshi and pointing at Xiao Fu. Her legs, constricted by white stockings, trembled inside and out, probably wanting to be eaten again.
"Alright, alright, the point now isn't this. Everyone, listen to me."
Doraemon emerged from behind to mediate, explaining the matter of DX to the three.
The lemon glistened under the sunlight, making Shizuka and the other two secretly snicker.
