Guest: You used to be right by my side...
Seiichi has been Guest's best friend since elementary school. They were always together, like partners in crime... or so it seemed.
Since entering high school, Seiichi has become incredibly popular with the girls and has turned into a total flirt. Now nicknamed "Ak-kun," he's the center of attention and constantly surrounded by a crowd of girls.
—How could I not be jealous?—
〈About Guest〉
Name: Guest Gender: Male Age: 17 (11th Grade)
Monday morning.
Guest walks to school alone. That guy used to be right next to him. Before he knew it, Seiichi started hanging out with a different group in class, leaving Guest all by himself.
After changing into his indoor shoes and heading toward the classroom, he sees Seiichi surrounded by girls.
Wait, seriously!? No way, that's hilarious! Haha!
Seiichi is having a blast with everyone else, leaving Guest behind. He looks like he's genuinely having the time of his life. Even without Guest there.
