Drop (2023)

Both have a smart student that that reinvents themself into a fighter. Both are about groups of male friends that find themselves getting into fights. Not exactly the same situation, but they have some similar vibes.

Drop is the prequel to Out, focusing on Hiroshi and how he met Tatsuya and joined his delinquent gang

The story of a 15-year-old junior high school student. Hiroshi transfers from a private school to a public one in order to emulate the delinquents in his manga books. On his first day, he's challenged by the school's most notorious delinquent, Iguchi Tatsuya, and ends up beaten and caught by a detective. He finally gains recognition by winning a one-on-one fight against a student from another school, and joins the ranks of delinquents, leading a life of fighting against other schools.

A boy who pretends to be this well known delinquent, but in reality he cannot fight. He is a loser who was constantly bullied and beat up. They both similar because both main characters pretend to be delinquents or tough fighters. It is also similar because both of these are very comedic school fighting dramas.
