I Wanna Do Bad Things with You manga volume 1 features story and art by Yutaka.

Mamori Wataya is used to being a nobody. She lingers in the shadows of her high school, dismissed by everyone around her—that is, until she meets Soshi Fuji, the school's notorious troublemaker. Fueled by her deep admiration for villains, Mamori quickly becomes captivated by Fuji's devil-may-care attitude, and together they embark on a rebellion against the status quo.

After discovering that Fuji lives in the shadow of his popular and perfect younger brother, nicknamed "the Prince" by all the girls at school, Mamori offers to help Fuji derail his brother's campaign for student council president. But as Fuji's audacious pranks pull them closer together, Mamori discovers there's more to like about Fuji than his just villainy.
