So This Is Pain Manami Sangaku X Depressed!Reader

Manami finally feels the pain he's been wishing to feel but it's not as good as he thought it would be.
I'm sorry :,( but I had and idea and I had to write it.
Plot and story belongs to me.
The picture doesn't belong to me.
Manami Sangaku belongs to Wataru Watanabe.
You belong to you or Manamis heart if you wish.
