pairing studying and fighting really reminds me of old j drama like gokusen or rookies. teaching students who know how to fight and not study or the students who are good at fighting find out how studying can help their life on the long run

In both drama there is the theme of parallel universes/time travel and there is that handsome and popular×clueless when it comes to love dynamic between the pairing.

both drama are historical and in both drama, the fl is going through a lot of adversity and difficulties but stays resilient throughout and the ml is deeply in love and is able to do anything and everything for his love no matter how it impacts his life.
