What do y’all mean by “revenge story” what’s going on

So the crazy boss man - who is scared of horror movies - sorry I don't remember his name - told Yeonwoo that Geonho killed his close friend and respected older brother in the gang that he used to follow around - as Yeonwoo is a cute little puppy as we all know. Whether Geonho actually killed him or not we don't know, but we do know that Geonho feels sorry about the death of Yeonwoo's close friend, so he may have been involved or at least he probably knows what happened. It seems likely that Yeonwoo approached Geonho after he got out of prison on the behest of crazy boss man to take his revege for the death of his friend. Only it seems Yeonwoo has caught the feels, so now he is a bit recultant - also because he is a cute little puppy as we all know. Anyway that's what I understand thus far. Hope any of that makes sense.
Ight me and who??
