Won-joon tells Kim-gyu-han that he doesn't mind that he likes him because he treats him like a friend. He hopes that if he acts like nothing is wrong, he'll be able to get back to normal, and that's what he's hoping for. Kim-Gyu-Han is all, "Dude, why are you still liking him?" and won't stop until he gets the answer he wants: "Why do you always look disgusted?" and "Why don't you just smile when I'm with you?" and so on. He's got a point, he says, but why does he always wear that frown when they're together? If he used his powers, he could know his real feelings. He says, "If I used my powers, I could at least at least know you're real feelings," and he apologizes for crossing the "line."
