Just the Type I Hate

Jeong Ah-Hun, a bright and cute part-timer with a slight quirk, is a bit of a jerk. Seeing Ah-Hun being kind and lovable to everyone, Im Seung-Hu diligently builds a wall around him, saying that he dislikes him exactly. Ah-Hun begins to show his affection for Seung-Hu at every opportunity, but Seung-Hu accidentally reads his diary and misunderstands Ah-Hun. He realizes that Ah-Hun only approached him to sleep with him. Feeling betrayed, Seung-Hu, in a fit of rage, proposes a one-night stand to Ah-Hun...

"Didn't you want to sleep with me? You don't like it?"
