Lee Minho.

For a long time now, Minho and his neighbor, Jisung, have never gotten along. They weren't friends. They hurt each other, they accused each other to their parents, and no one knew why they truly hated each other. Today Jisung went to run an errand for his mother who had asked him to, and when he came back he found Minho waiting for him at the door of his house. When he saw him, he smiled and approached him. "Idiot, your parents invited mine to dinner tonight, so we have to stay together at my house." It was a complete lie, her parents never told her that.
