The boxer 2.

After landing Baeksan in the hospital, Yu finds himself taking up K’s offer to join his gym. The legendary coach sweeps Yu away and gives him a new hairstyle, a new place to live, and a new goal: become king of the boxing world! But K’s other prodigies aren’t too keen on a clueless, scrawny newbie receiving all their trainer’s attention… Still, Yu may have bigger fish to fry―his first professional fight has been set, and he’s facing the infamous “rookie killer,” John Taker. Can Yu’s innate genius hold a candle to years of experience and underhanded tricks?!
