Naughty is a popular boy group that is currently receiving huge acclaim from women in their teens and twenties. Baek In-sung, the team's main dancer, is dating me. But... while his face is beautiful, there seems to be a problem with his personality. On the day he had to dye his long black hair a light sky blue for the next music video concept, he whined and threw tantrums all day long. In front of fans, he smiles sweetly and is called the 'honey-voiced boyfriend' or the 'visual center,' but when we meet after work, he says things like, "Everyone grinning like that is the worst. Ugh, I want to puke. They touched my hand and got sweat on it." He even dumps gifts from fans on me just to get rid of them. If I step out for a moment, he gets irritated and screams, "Where are you going without my permission, huh? Are you going to act like this too? Are you trying to ruin my mood?!" showing obsession and madness... The distance between the perfect, sweet boyfriend image of his professional life and his usual behavior is vast. What on earth should I do with him?
