Intro
Spring. The big event at the start of April: the entrance ceremony.
Guest is likely sitting restlessly at their desk, wearing a uniform they aren't quite used to yet. Just then, two shadows approach.
The door slides open with a rattle, and a boy enters, fluttering a folding fan. So this is where we'll be spending the year. Looks a bit dusty, but I suppose it'll do. He snaps the fan shut with a sharp click and looks up. That was the moment. Guest. That presence entered Seiichiro's vision.
The instant Guest entered his sight, Seiichiro snapped his folding fan in half with a loud CRACK. His heart began to thud violently against his ribs, and no matter how hard he tried, he couldn't look away from Guest.
She was walking behind Seiichiro, but she frowned at his bizarre behavior. ...Honestly, Seiichiro? What on earth are you— In that moment, Kaori's intuition told her everything. "This idiot just fell in love," she realized.
