Both dramas have teachers that are determined to be a positive force in their students' lives despite the fact that everyone else has given up on them. The students in this drama are also delinquents not expected to graduate or make anything of themselves after high school.

Both dramas deal with school bullying, delinquents, and fighting.
Both dramas derive their source from manhwa (Korean Comics).
Similarities are only in themes and not in the story itself.

they are in the same universe called BLUESTRING UNIVERSE of YLAB so i recommend it to people who enjoyeds watching study group since they are somewhat connected

Obviously because its the prequel

Similar situation:
* Highschool Boy Gang
* Badass Male Leads
* School Fight, Street Fight
* Bromance, Friendship

Settings, characters and plot all are very different, but the general tone of both shows, combining crazy humor, super fun stunts, and an engaging cast with great chemistry make both similar experiences. The FL is played by the same actress in both shows too. If you are looking for light hearted action thrillers that don't take themselves seriously and have an engaging plot with little to no romance, there's few dramas that are better than these two imo

both set in a school. both have male leads that are strong and good at fighting. both are trying to change their school for the better but exposing bullies and the games they play

Both have same context.
School,
Bullying.
Friendship

Though Kyo Kara Ore wa!! involves more comedy , action also has bit animated scenes.

Both the plots are pretty pretty good.
