HELP

I need to find a BL manhwa
MC got his gf pregnant when he was young, she left him with the child and mc's family gave him a fake university title (for law I think) since they have connections
MC's son got a gambling debt and the mafia boss knows his uni title is fake and black mails him with it and forces him to have sex since he doesn't have enough to cover his son's debt
I only read the first 3 chapters so that's all I remember
Help me please ┗( T﹏T )┛
