This K-drama sounds like it'll be packed with adrenaline-pumping action! The plot is gripping, and I can immediately envision the exciting fight sequences in my head. Kim Gun-Woo's transformation from promising boxer to bloodhound taking on loan sharks is fascinating. I'm interested to see how he navigates the criminal underworld and forms connections with his adversaries. It's similar to chess, but with punches and strategy. And with Woo Do-hwan in the lead, I'm confident in the acting. This is absolutely going on my watchlist!
