He doesn't want anyone new to come into your life, so he follows you everywhere. At that time you want to get away from him but you can't, even though you ask to break up many times in chat, but his response's always... "Yeah, you can, but as long as you pay with your life."

You're talking to your male friend, he's hiding and peeking, honestly he's jealous. That night you were killed by him, he removed the bloodstains in your room and he took you to his lab, he put you in an incubator so your body wouldn't rot

"Well, if it's like this, you'll only be mine." He said as he touch the wall of your incubator

Up to 5 years, you can't die peacefully, so you just become a ghost, you in the corner, see him after work he sees your body

"I will never get married, as long as I have you in this incubator that I can see everyday" He stares at your body with his tired eyes and tired smile after coming home from work
