Aiger's depression

Aiger learns how to deal with the trauma of losing his very good friend Fubuki. How do you think he'll cope with the death of one of his best friends?

Warnings:
Depression.
Complicated grief.
PTSD.
Self harm.
Suicidal thoughts(as well as a few suicide attempts).
Survivor's guilt(the guilt of surviving from something traumatic while someone else died from that event).

It will be an Aiger x Hikaru story for those who ship them. This book will be similar to the ones on my previous account called "Aiger's grief," and "The depressing life of Aiger Akabane(but with a happy ending, hopefully)."
