@RoryMercury, the tags are indeed misleading a bit but not incorrect either. You might wanna add Psychological (maybe? not sure what are the criteria). It's not focused on training/combat/competition enough to get a Martial Arts tag imho. Maybe an Action tag instead?
Appart form that, unless you make up a "not a romcom" or "not generic korean webtoon" tag, it's hard to categorize it.
Hopefully it won't be as simple as "my father beats me so now I'm a bully", many people are abused and don't become abusers, you're still a piece of shit for not learning from your own pain.
