Rain, a handsome guy, has car trouble on a rainy day. Fortunately, Phayu, a charming motorcyclist, comes to his rescue. Rain is completely captivated by Phayu’s gaze the moment he takes off his helmet. It turns out that Phayu is actually the famous upperclassman and the dream guy of all the girls—including the girl Rain had his eye on—which is why Rain starts to feel a certain dislike for Phayu. They meet again when Rain’s car breaks down once more. That day, Rain has to spend the night in Phayu’s garage. Phayu starts teasing him again and acts as if he wants to touch Rain. For this reason, Phayu becomes Rain’s number one enemy, and Rain wants to expose Phayu’s true nature to prove to everyone that he isn’t as great as people think. Since Rain can’t beat him, he tells Phayu that he’ll make him fall in love with him within a month.
