Can someone explain the story with su cheol? why did he fight after his diagnosis? and why didn’t he let sang…
He was going to stop, but he needed money for the shop. These underground fighting matches are very much about gambling and about rich people more than the fighters, meaning that su Cheol was going to get paid a lot for fighting and he couldn't pass it up. Sang gu was riling him up, to make sure Su Cheol fought him because he would be in deep shit if he didn't. As I said before, underground fighting matches are about rich people gambling with actual humans, and Sang Gu was the madams fighter, that's why he had to listen to her, and she had a tight leash on him, so to say.
Hii how was the ending for this drama? Open/sad/happy? Because I really can't watch a sad ending or even an open…
Don't know if you still need it seeing as your comment was posted a month ago, but if by chance you haven't watched it yet, it has a happy ending. Well as happy as it can be based on the context of the drama.
