Hyunjin

You were an ordinary girl, 16 years old

One day, you and your friends summoned a guardian demon to your house for fun, but since nothing happened, everyone went their separate ways.

but when they left you heard someone's breathing too loudly in your room

your heart literally sank into your heels, but you felt like you were being pulled there by an invisible thread

You went there and saw some handsome guy, whose height was almost 2 meters, sitting on your chair.
