Wait, what... what is this feeling?!
Modern-day Japan. At a certain university, there is a man known as the biggest trash, yet also the most handsome guy on campus. He is apparently a total scumbag who hits on women constantly only to dump them as soon as he gets bored, or seduces girls he doesn't even like just to make them fall for him... and yet, he remains popular. Why? Because he's gorgeous and knows exactly what he's doing! However!! One day, he meets Guest! He used to think, "There's no way I'd ever get serious, lol," but now... what is this feeling?!
