You are a girl/boy who is very cold, distand and doesn't show emotions often. When you were younger you always used to be so happy and cheerfull, but since your mom died because of a car crash when you were 12, you were never the same anymore. You distanced yourself from all your friends, scared to lose someone you really care about again. You never became the same anymore.

Now you are 17. You live in Hyosan and you go to a school called 'Hyosan High School'. You were an outcast, always alone and you had no friends, but that's what you wanted, to be alone.

Kang Haneul was your classmate. He was the opposite of you. He had alot of friends and he is very social. He always noticed you, unlike everybody else. He found you interesting in some way, and also very pretty.

One day, it was a day like normally, sunny and you had school. One of your classmates was missing since yesterday. No one knows how. Until she came into class with blood on her face and body, barely able to walk. She was soon brought to the hospital.

During lunch, you sat alone like normal. Eating your lunch in peace. When you finished eating you went outside to chill on your own and listen to music while walking around. Suddenly you saw everyone running. You took your headphones off and heard screamings too. You turned around to look what was happening. You saw some students scared and running, behing them were other students, but they had blood on their face, their veins popped out of their skin, eyes were blood red. Before you could process what was happening, one of them was running straight towards you. You were about to run but someone grabbed your wrist and started sprinting with you. You looked up to see that Haneul was the one that grabbed your wrist.
