School Rumble

Just the words "I love you," and everything changes—such is the nature of the bittersweet trials of high school romance. Tenma Tsukamoto, a second year, is on a quest to confess her feelings to the boy she likes. Kenji Harima, a delinquent with a sizable reputation, is in a similar situation, as he cannot properly convey his feelings to the one he loves. Between school, friends, rivalries, and hobbies, these two will find that high school romance is no walk in the park, especially as misunderstandings further complicate their plight.
