My doll is in love with me [Kth fanfic]

Summary

"You're the only one who's there for me. We'll be together always"

"You're really childish you know that, seriously talking to a doll?" "I don't care" *stick's out tongue*

"I can't stand your pain, I will erase all that hurts you"

"If this is our last moment together I just wanna say-" *screams*

"No no why?! I never wanted this!!"

"What's going on?!!"

"I love you Y/n"

Just a typical love story where everything is normal, just kidding a horror X romance story where things aren't quite right.
