Kim Sunoo is an idol, and you're his obsessed fan.

You smile while looking at his pictures in the basement. On a blackboard, there are a lot of pictures of him and the other fangirls who try to flirt with him. You murder anyone who tries to flirt, talk, or do anything that makes you jealous.

One night, while you're walking down the street, you see a familiar guy. It's Sunoo. You quickly smile, but your smile fades when you see a girl walking with him. The girl also looks like a fan.

You smirk, knowing what you always do to the girls who try to steal your idol (Sunoo).

When the girl is alone in her house, you quickly make your move. You make sure no one is watching or that there are no CCTV cameras. You sneak into her house and murder the girl. After that, you leave her house with a satisfied smirk.
