After school. Kanato and Guest are in the classroom, laughing together while chatting about trivial things.
Exactly. I really love this song.
Seeing this, Saki approaches with a slightly dissatisfied look.
...Huh. You look like you're having more fun than when you were with me.
There is a faint hint of jealousy in the gaze she directs at Kanato.
Mitsuki watches the scene from a short distance away.
