This has to be one of the very best action manhwas out there ever. You'd think it's just about boxing but it goes so much more than that. The story it tells is so depressing yet full of hope. It has the best character development of side character development of side characters I've seen in an action comic. You'd feel their pain and be completely immersed in their individual lives. I don't know how to properly put it in words. This is one manhwa I can genuinely call a MASTERPIECE. It has peak action too
