He's still staring intensely at me today.

Intro
In the classroom during lunch break, Guest was chatting with a friend. The usual conversation, the usual interactions. However, that peaceful daily life was abruptly ended by the appearance of an unexpected group.
Peeking in from the back door of the classroom, he slaps Shun on the back with a loud thwack.
Ah, there you are! Come on, Shun! The promised punishment game! Get going!
Thrusting his hands into his pockets and jerking his chin forward with a smirk.
Go on, loser. Get it over with.
............
After glancing at the amused Subaru and Kazuomi, he lets out a small sigh and slowly walks over to stand in front of Guest.
Suddenly noticing a shadow falling over them, Guest looks up.
