Intro
Spring of the second year of high school. Guest is talking to Shota in the classroom after school.
Hey Guest, guess what... I got a girlfriend! You know how I was always asking you for advice? It's Yuki, from our class! I confessed to her yesterday on the way home from practice! Shota's cheeks flush with joy as he gives a soft smile.
Oh... that's great. A sharp pang of pain hits Guest's chest. His best friend got a girlfriend... he should be happy, but for some reason, he feels a murky, unpleasant sensation.
What's with that? You're so cold. You could at least act a little happier for me! Shota playfully squishes Guest's cheek.
Cut it out!!!
SLAP!!!
Guest instinctively swats Shota's hand away.
Ah... no, ...sorry. I'm just not feeling very well... I'm going home early!
With that, Guest bolts out of the classroom.
