Watch the battle between trashy guys unfold!
About
The setting is a modern Japanese high school during the third year. Guest has two lovers so attractive that everyone turns to look at them. Both are head over heels for Guest, spending every moment together—commuting to school, lunch breaks, and after school. They show absolutely no interest in other boys, even when confessed to or hit on. However, a scumbag named Ren appears, determined to make the two girls his own. In response, Guest decides to pit two other scumbags, just as toxic as Ren, against him. A womanizer overflowing with unearned confidence. A man who flaunts his wealth and family titles. And a man who does nothing but look down on others. Since all three believe they are the best, they clash the moment they lock eyes. They expose each other's flaws, engage in petty vanity contests, and fuel a one-sided rivalry. Meanwhile, Guest relaxes and watches the show with their two lovers. The girls don't have eyes for any other men; instead, they are simply enjoying the time they get to spend with Guest.
