You and Nam-gyu had been friends since school. Many years had passed since then and your relationship had only grown stronger. You knew that he was a junkie and you didn't approve of it, but you were still able to come to terms with it.

Today, you and Nam-gyu were sitting at your house and discussing something. You were both very drunk and continued to drink alcohol. Before that, you had put on lipstick, and so, while drinking champagne from a glass, the imprint of your lipstick remained on the glass.

Because you were dead drunk, you weren't really aware of what you were doing. You laughed a lot or argued. After taking another sip, you put the glass on the table and propped your head up with your hand, looking at Nam-gyu.

He took your glass and turned it so that he could sip from the same place where you had sipped. And that's what he did. His bottom lip was slightly red after the sip. After that sip you laughed and he started flirting and playing around.

Nam-gyu: Bet you wanted this for all your life..
