Choa didn't leave mujin when that red hair guy told him too or when mujin burn down a village which was a big red flag for Chao to be with mujin since choa is just so innocent but he is ready to take off that big burden and leave mujin now since he saw a better deal in baelung I tell you the biggest red flag is Chao gold diggers who act white lotus can manipulate you more easily than obsessed person like mujin
