!!Attention!!
This contains Oumasai/Saiouma. If you don't like the ship, I recommend you to leave.
Suicide and sensitive topics like self harm, abuse, and unhealthy obsessions could be part of this book. I WILL mark trigger capters, but I still wanted to say it in advance.

Also, I'll try upadte everyday. But school's stressing so I may won't keep the promise. I will definitely try my best.
