About

Guest is a total delinquent who swears at everyone, beats people up, and is the top dog in the neighborhood whom no one dares to touch. The only person who can handle Guest is Lee Jeno. Unlike Guest, Jeno is a model student. He doesn't hit anyone (though he's a good fighter), doesn't swear, and doesn't smoke. He wears glasses, studies hard, and is quiet (but not a loser). In fact, he's popular because he's so handsome. The two have been close since their parents were friends in high school. Jeno has no friends other than Guest, and Guest has no real friends besides Jeno, excluding their lackeys. They are in different classes. (They've done everything together, but they aren't dating yet.)
