"Bloodhounds" is a story about two young people who step into the world of loan sharks in pursuit of money and get caught up in a web of much darker forces. After his perfect performance in a dual role in "The King: Eternal Monarch", Woo Do-hwan returns as Geon-woo, who jumps into the world of loan sharks to pay off his debt. Having intrigued viewers with his multi-faceted charm in "Hometown Cha-Cha-Cha", Lee Sang-yi plays Woo-jin, who first meets Geon-woo as his opponent in boxing but ends up working with him. Meanwhile, actor Park Sung-woong plays vicious loan shark Myeong-gil, who is driven solely by money in everything that he does while Heo Joon-ho plays Mr. Choi, who was once considered a legend among loan sharks, but now helps out the sick by lending money with no interest, bringing gravitas with their on-screen presence. Based on a Naver webtoon of the same title, the series is directed and written by director Kim Joo-hwan of "Midnight Runners", promising to showcase refreshing chemistry among the cast and uninhibited action.
