Nanba MG5

Both titles have the Yankee/High School/Hidden identity themes in common and of course the comedy aspect!

Both have similar vibes, though the plot is slightly different.
Its about about school delinquents.
will be updated as this progresses.

Tsuyoshi Nanba (Shotaro Mamiya) is a troubled student, who is good at fighting. His delinquent behavior comes naturally to his family, which includes his parents and two siblings. When his parents were students, they were also trouble makers. Nevertheless, Tsuyoshi Nanba wants to become an ordinary student with good grades. He hides this desire from his family. After he enters high school, Tsuyoshi Nanba begins to lead two different lives. At school, he wears his uniform appropriately and behaves like a model student. At home, he dresses like a delinquent and behaves accordingly.

Tsuyoshi Nanba has now become a top student and has even joined the art club. One day, he sees a student being bullied by other students. Tsuyoshi Nanba changes out of his school uniform and dresses like he does at home. He saves the bullied student. Since then, students at his school talk about the mysterious delinquent student that saved a bullied student. I think both yun gamin and nanba have similar characteristics

Though the story is totally differnt, the leads in both the series lead double lifes.
Nanban is slightly more hilarious.

School setting. Delinquents . Few Fights . Good Comedy.

Both have very similar vibes, however the main plot is slightly differently. (In one series one disguises intentionally and in the other it happens accidentally in the beginning).

Very likely who enjoyed the one would enjoy other as well.

Note Korean series is emotional and seems to have melodrama.

Both are about daily life of high schooler delinquents, similar vibes of comedy, violence, and friendship.

The most powerful yankee, Hurricane Aida is reformed, and secretly enters high school becoming the class representative, and then student president.
However her past comes back to haunt her.....

(Pretty much the same plot with the genders reversed)
