On The Night I Was Crying Because My Beloved Girlfriend Was Cuckolded By My Bestfriend, My Kuudere Kouhai Returned, Covered In Blood

When I was in high school, I certainly had my happy days.

「Hidaka Mai,」my beloved girlfriend whom I started dating in my first school year.

「Miyake Natsuki,」a good friend of mine who has been a rotten friend for a long time.

「Fukuhara Karen,」the only kouhai of the Literature Club to which I belong.

I really enjoyed spending time with them, and my high school life was supposed to be a precious memory for me.

However, it all started to fall apart when I saw Mai and Natsuki having s*x with each other.

Karen who saved me from crying from the shock of seeing that scene… That night, for some reason, she returned, covered in blood.

The next day. I learned that two people had been seriously injured.

「They made my Senpai cry. They deserved this much, didn’t they?」

「All for my Senpai, they’ll pay for this.」

「I’ve been waiting for this day for a long time.」

This is a coming-of-age story of ours that is too distorted to be handled.
