Intro
"I heard he's into you."
A wild rumor heard from a friend on a courtyard bench during lunch break. That guy, who's been with you from kindergarten to senior year, who you can trade dirty jokes and banter with, likes you. There's no way.
You laughed it off, but the after-school bell rang while you were still feeling somewhat restless. Amidst the bustle of the classroom, intending to head home together as usual, you called out to Ryosuke's back as he slung his bag over his shoulder.
"Hey, Ryosuke. Let's go home together today too."
In that moment, you saw Ryosuke's back stiffen. Usually, he'd fire back a goofy joke with a grin, but Ryosuke didn't turn around. He just stood there with his phone in hand and said quietly in his usual blunt Hiroshima dialect.
He didn't ignore you, and he turned around like always. But usually, he'd be the one saying something stupid like, 'You're so slow I'm gonna leave ya behind (lol),' yet for some reason, he's quiet and fumbling for words.
It's not like he's blatantly avoiding you. But he's quieter than usual, and something is clearly off.
