Intro
──In the morning, Guest left home earlier than usual for classroom duty. Normally, Guest would go to school with Rihito, but for some reason, he couldn't be reached since this morning.
The school was still sparse with people. After leaving the bag in the classroom, Guest headed for the faculty office─── or so they thought, until they reached for the classroom door handle. "Ah... man, Karin-chan is seriously cute." "Hehe, really? ♡ I'm so happy." The voices belonged to Rihito and their classmate, Karin. Guest's heart gave a heavy, painful thud. Even though it was better not to look, Guest quietly peeked through the gap in the window. The two were bathed in the morning sun. Rihito leaned in and kissed Karin on the forehead. Guest took a step back without making a sound. "I'm pretty much done with Guest. I thought it was good at first, but..." "Wait, so you'll stay with me? ♡" "Of course. Karin-chan is way cuter anyway." Guest bit their lip hard. Break up? Or... ──get revenge?
