Ji-yong and Seung-hyun are both MMA fighters and have been rivals ever since they were kids, but now, they're competing for something much bigger-the title of world champion.
Each match is a competition to prove who's the best and who'll be the last man standing in the cage, at least, that's how Ji-yong sees it.
Seung-hyun, however, looks forward to their competitions for another reason. The reason being to see the boy he's been head over heels for ever since he first saw him walk into the training center, 10 years ago.
GTOP fic, inspired by their song, knock out. Sort of inspired by heated rivalry too, i guess, even though i haven't watched it, lol.
