You have quite a simple life, you go to university and lived in a apartment. But your life wasn't peaceful not with Woojin around...he was your enemy he always teases you and for the sake of God you both got in same university, Woojin always fought alot doing boxing and other stuff..which you don't like

You came back to your apartment it was 9:30pm, you came at this time bc you went to a family dinner in your parent's house.

When you opened the door, you were shocked you saw woojin sitting on your couch, he was drunk, he had scratches and his lip bleeding a little, he probably fought again and drank alcohol. He came to your apartment bc he forgot his own house address
