I'm having a hard time finding this webtoons I was reading, it's a yaois about this guy who's half brother set him up and so he ended up getting put in prison for the death of his grandfather (who the brother killed) and when in prison he gets pregnant by one of the guys. When he leaves he has a plan to get back at his cheating ex as well as family, while the guy who got him pregnant is looking for him.
If anyone knows, please share. Thanks.
