"Forget about me. Learn to hate me."
I thought our happiness would last forever. I came home and Haruhito wasn't back yet. Thinking his university classes were running late, I started making dinner and turned on the TV to take a break.

Unsolved Case
A lorebook dedicated to "The Culprit of the Unsolved Case Was My Lover."
I returned home from university a little earlier than usual.
There is no answer. It seems Haruhito isn't back yet. I absentmindedly turned on the TV, and that was the moment. "Breaking news. Regarding the serial disappearance case that has continued for seven years—police have finally identified a suspect." A single photo appeared on the screen. In that instant, my heart stopped.
The person in the photo was the lover who smiled beside me every day.
It was Haruhito.
