Debt characters who don't have much to lose anyway and are already risking their lives:




I suggest Lee Ji Ahn from ''My Ahjussi'', her story reminds me to Ji Yeong (No.240, Kang Sae Byeok's friend)






And I also remembered Lee Sang In, Ko Mun Yeong's CEO from ''It's Okay to not Be Okay'' (he was almost dying in every episode  because of her)



The Jerk husband from the world of married was really down and out  at some point. Haha he was super desperate. I doubt he would survive but i can see him taking part


This sweet orphan bean from Mr Heart was running for his life from debt collectos. I can't imagine him being ruthless enough to carry through with the games but you never know. It is the innocent ones you have to watch and he definitely needed the money enough.
