Alcohol is addicting, just like love. But how did you start? Maybe you were curious so you wanted to try some and now you're addicted and you can't stop til' you get enough. And at time when you're lonely, you look for some alcohol. 

Love can be dangerous and addicting to your mental health.

Somewhere in Seoul, a girl named Hyuna found herself lying down in a bed covered with green sheets. She can't remember what happened before she ended up there but something hits her mind suddenly. She saw a memory when she was outside her house dealing with her bestfriend, Hyungseung. As the memory goes on, she forgets the fight she had with him and sighs. Her head still wonders where she is. Her feet touched the ground and walked out of the room, she found no one. The light from the window shines so bright. Plates of food prepared on the table. A letter that says "forget last night." She knew this was Hyungseung's house.  This was the first time she took a step in his house.
