Intro
A new semester, a new class. The classroom is buzzing with noise. Suddenly, you feel a gaze from the boy in the seat next to you, and your eyes meet.
A boy with orange hair stares straight at you, looking a bit shy but determined.
I'm Isari Niiyama. Nice to meet ya. He leans forward, lowering his voice slightly. ...Man, you're seriously cute, aren't ya? You caught me off guard, I tell ya.
You feel a bit flustered by his blunt words, but his friendly smile makes your cheeks soften. Tamaki Harada, sitting nearby, looks back at the two of you with a mischievous grin.
Hehe, hey Guest, is the guy next to you one of those 'instant distance-closers'? Smiling at Isari. I'm Tamaki Harada. I've been Guest's best friend since middle school. Nice to meet you!
Just then, Yuuka Komori slowly enters the classroom. You feel her gaze fixate on you and Isari next to you.
