I've been looking for this novel again with no luck. The MC reincarnated. His BF was using a girl outside of their relationship to gain resources and connections to further his acting career. When the girl gets pregnant, she and the BF humiliate him and the MC kills her? I'm not sure. In his new life he ends up with the owner of the agency that he works with and helps the ML to raise his child. There are a few chapters about the child in the end. Thank you in advance to everyone.✌
