"Momo, where did you go during P.E. class?"
"Mmm… nowhere."
Back in the classroom, Momo faced Nana's question and shook her head.
"So suspicious… did something happen?" Nana stared at her doubtfully.
"Nothing… this kind of thing is still too early for you." Momo glanced up at Nana with a faintly mocking look.
"What's with that expression! Too early for what?"
"Don't ask."
"You didn't… go see him, did you?" Nana frowned as she asked.
At this school, the person Momo was most likely to run to was obviously him.
"It's not like there's much to do in P.E. anyway." Momo didn't deny it.
"You really went to him! Then the two of you alone—did you do something?" Nana couldn't help asking, her mind racing.
One particular scene floated up in her head: that moment when they'd just come back, when she'd been in Momo's body and got kissed by Shichen. It was a scene she still couldn't shake.
What bothered her most was that even now, that guy had never mentioned it, acting as if nothing had happened at all!
Was her kiss really that unimportant?
"What did we do~? Do you want to know?" Momo smiled sweetly at Nana.
"Wh—who wants to know!" Nana denied instantly.
"Haha~ Nana, you clearly care a lot~"
"I don't care at all!"
"Actually, brother-in-law and I didn't really do anything."
"You think I'll believe that?"
"Really. If you don't believe me, smell this—there's still a scent." Momo blew a breath toward Nana.
"What… is that? So weird!" Nana just sniffed once and immediately pulled a face, pinching her nose and leaning her head back.
"Really? I think it smells pretty good." Momo cupped a hand to waft it back toward herself and took a whiff, eyes curved in a smile.
"What did you even eat?" Nana asked.
"Hmm~ Anyway, it's something Sis likes too," Momo thought for a moment and answered with a grin.
"Seriously?"
"If you don't believe me, you can ask Sis," Momo said confidently.
"What is it exactly? Can't you just tell me?"
"Even if I did, you wouldn't understand. You'll definitely come to like it in the future."
"No way!"
"If Sis and I both like it, how could you not? Unless you're not really our biological sister."
"How could that be!"
"Though now that I think about it, it is a little suspicious. Sis and I aren't small, so how come you're so flat?" Momo looked seriously at Nana's chest.
"You're asking for it!" Nana exploded.
…
At noon, back home, Nana couldn't resist her curiosity and went to ask Lala.
"Sis, is there any food you especially like?"
"Food I really like? I like everything Shichen cooks~" Lala answered with a smile.
"Then has he ever made anything… weird?" Nana pressed.
"Nana, what are you even talking about?" Lala tilted her head, confused.
"Forget it… I knew I wouldn't get anything out of you." Nana sighed and gave up.
"Eeh~"
Nana didn't go ask Shichen. She'd barely had a proper conversation with him, and with Momo right there, there was no way she had the nerve to bring it up.
But she was still very curious.
Would she have to find a chance to ask that person directly?
In the afternoon, back at school, Shichen lounged on the office recliner, a satisfied look on his face.
Given Momo's energy and initiative, she probably wouldn't take long to get very "skilled" at this.
Honestly… how sinful.
"Brother-in-law~"
A playful voice broke into his thoughts.
"Momo, you again?" Shichen looked at the pink-haired figure walking in through the door.
"Hehe~ This period is home ec. The stuff we're learning is way too easy, so I snuck over here~" Momo shut the door and walked toward him.
"P.E. in the morning and home ec in the afternoon, that's a pretty easy schedule," Shichen muttered.
"What are you talking about? Isn't this your school?" Momo walked behind him, hesitated a second, then placed her hands on his shoulders and started massaging.
"Even if it's my school… ah, forget it." Shichen shook his head.
"You're so weird, brother-in-law."
"You don't understand my past… hmm? Your technique feels off today." Shichen noticed her massage felt different, clumsier than usual.
"R-Really?" Momo's face flashed with panic.
"Do you need me to do something? Just tell me directly, no need to be polite with me," Shichen chuckled, not bothering to look back.
Momo secretly exhaled in relief. "Y-You really are smart, brother-in-law. You even figured that out."
"Flattering me? Sounds like this isn't a simple favor." Shichen reached up, grabbed her wrist, and with a tug pulled her down onto his lap.
Momo's body went stiff, completely frozen.
Unconcerned, Shichen wrapped both arms around her waist, then lowered his head to plant a quick kiss on her. "Come on, tell me, what do you want?"
"N-Nothing really…" Her cheeks were scarlet, lips pressed together, expression a little blank.
"Still saying it's nothing… If you want something, just say it. Why be shy with me?"
"Mmm… Actually, I wanted something delicious…"
"Huh?" Shichen gave her a strange look.
Momo wasn't usually a little foodie. And the "Momo" in front of him felt… off.
"W-wait—!" Momo trembled all over, as if trying to stop herself from talking.
"Wait for what?" Shichen flexed his fingers, smiling.
"N-nothing…" She bit her lip and shook her head.
"Heh, hurry up and say it."
"…The same as this morning."
"This morning… huh?"
"Wh-What's wrong?" Momo asked nervously, something in Shichen's eyes making her uneasy.
"Nothing… Are you serious?" he asked.
"Eh?"
"'Eh' what? Forgot you helped out too?"
"I… did? Oh, right, I almost forgot, hahaha~" Momo laughed awkwardly.
"In that case—" Shichen scooped her up in his arms and headed for the hidden room.
"Eh? Where are we going?"
"To the secret room."
"Why the secret room?"
"What if we get caught?"
"Caught? Why are you afraid of being found out?"
"Because that's…" Shichen leaned close to her ear and quietly explained.
"Eeeh—!" Momo yelped in shock.
"H-How can that…! She… Sis…!"
"I knew it was you, Nana," Shichen laughed.
So they'd swapped bodies again. He didn't know what the two sisters were plotting this time, but it definitely wasn't anything wholesome.
"Y-You noticed?" Nana said, flustered.
"Your acting's gotten better, but the experience is different."
"B-But she really does like it…"
"Enough! You pervert!" Nana snapped, face burning.
"I'm the pervert?" Shichen teased.
"I didn't know what it was! Momo tricked me! And how could she do something like that…!" Nana's feelings were a mess of irritation and embarrassment.
"Isn't it a perfectly normal thing to do?"
"Absolutely not!" Nana's cheeks flushed bright red.
"Hehe~ You won't understand till you've tried it."
"I don't want to! Also, put me down!" Nana started to struggle.
"No can do. You walked right into my arms; how could I possibly let you go now?" Shichen held her tighter.
"Y-You… what are you going to do?"
