Gunwook is the prince of AO high school, every girl wants him except you. One day you called Gunwook to the rooftop, he appeared. "Why did you reject my friend in such an embarrassing moment?!" You said. "So?" Gunwook said and came really close to you. You freaked out and kicked him, making him fall down the stairs. You had to bring him to his place until you found out that he lives in the same building as you. You were cooking for him and you turned around and saw him shirtless.
