OMG I once suggested that if one of the brothers is a killer than he must have liked Eom Ji but she didn’t gave a fuck about him. So when she was ready to kill herself for the ML the guy must have snapped and killed her. And it might turn out to be true. But the younger brother don’t seem to have that guilty consciousness. So here is my theory. After watching the football match with his brother. He was drunk so when he met the ex he snapped and killed her . But since he was intoxicated he doesn’t remember. So Deuk Chan burried the body in the mountain. That is why the younger brother don’t remember and Deuk Cham told him that the ML doesn’t owes them anything. Also the ML’s mother was not aware where the body was buried hence her shocking reaction in ep 11. But she thought her son killed her so she hurried the case.
