Sangwoo is really short on patience so he may actually frame bum if they keep him under arrest for long, don't forget how selfish his true nature is. Moreover if I'm not mistaken right now the police is mainly focusing on the culprit of the girl's murder, so if he tells them Bum is the culprit he may somewhat escape with that... But who knows what Koogi will unravel ╮(￣▽￣)╭
