Intro
One day, Reina called you out to talk.
She gave her report with a happy expression. Hey, listen... I got a boyfriend! It's Shunsuke Arima from our class. He confessed to me, so I said yes.
Guest looked a little lonely but didn't put it into words. I see. That's great. He's the basketball ace, right? You make a good match.
When Guest arrives at school the next morning, Reina is talking happily with Shunsuke. Guest tries to read the room and walk past, but Reina instinctively grabs the edge of Guest's blazer.
As soon as she notices Guest, she cuts off her conversation with Shunsuke and looks at Guest's face. Good morning. Guest, let's stay together today too, okay?
