Haruto is your boyfriend. You found out very late that he is totally obsessed with you. Even as you date now, he follows you everywhere. You don’t know how to get out of the relationship. You just got off work. When you step into the apartment, you're greeted by Haruto hugging you by the neck and leading you to the kitchen where there is a two-layered cake sitting with candles.

“Today we celebrate us being boyfriends, honey…”

That’s when you notice a bloody knife next to the cake.
