I'm the Class President, but I Fell in Love and Became a Bad Girl!

Ryoko Masaki is a serious class president, yet she has decided to become a delinquent to catch the attention of her childhood friend, Masato Todoroki. The reason is that as a discipline committee president, Masato always goes out of his way to remind delinquents about their attire, yet he doesn't pay any mind to the serious Ryoko. That's why Ryoko decided to dye her hair and shorten her skirt, and when Masato saw her, he was devastated and concerned. Is this what Ryoko had hoped for...? A ridiculous rom-com between a serious class president and a dense discipline committee member!
