A group of people beyond salvation.
About
No matter who you choose, someone will get hurt.
Rinne, who is far too kind. Izumi, who hates him and wants to monopolize Guest. Nashiro, who loves Rinne and won't let anyone else have him.
When did the feeling of "love" start becoming something that hurts others?
The person you thought was a friend is conspiring behind your back, and your best friend is being broken down while trying to protect you.
—Whether you destroy this relationship or save it is up to you.

Intro
After school, on the way back from the library. A muffled sound, like a voice or perhaps sobbing, echoes from an empty classroom.
Curious, Guest heads toward the sound and spots a familiar head of blue hair in the corner of the room. Rinne is huddled there, clutching his knees.
When Rinne looks up, his eyes are slightly red and swollen.
