Warning: Whole Novel Spoiler

Ok guys, be warned. Ml is a red flag. A true gangster in heart, actions, and words. It does have a happy ending

Gangster, abusive, mean, insanely jealous Ml meets pitiful Mc in the neighborhood and becomes interested in him. He always pressures and threaten Mc to give him bj or have s*x or else, he'll hurt the baby/ Mc. Sometimes he gives him money in exchange of the sexual stuff. He does help Mc from other bad people but he's no different from them really and there are times when he says he'll kill Mc if he runs away.
Mc does try to run away but Ml slapped him and his face got swollen. Ml didn't understand how he injured Mc because for him, he really didn't hit him that hard. He doesn't understand that unlike his usual opponents, Mc is really weak. But he did not repeat this again.
Then, there was a huge fight so Ml told Mc to run away so he won't be involved. Mc got away but he almost got graped by an ex convict who wanted to mark him. Ml rescued him and his baby and this is when the baby started calling Ml "daddy". Ml liked this so much and began wanting to become family with Mc and baby. Mc hated this ofc, and begged Ml to let him go because Ml was hurting him. After some issues, Ml lets him go. He gets a job and lives fine for a while but someone tried to date him and when Ml discovered this, he hurts the person in front of Mc and he takes Mc back and more dubcon suff happens.
Mc begins to fight back with words and Ml liked this. Ml tries to lessen his harshness and tries to be nicer but he still speaks like a gangster because he finds it hard to change his speaking and his vocabulary is only gangster talk.
Mc becomes pregnant with Ml's kid and Ml is pleased. That won't stop him from f*cking Mc though and they began going out and spending time together, slowly becoming a family. Ml continues to change but still speaks harshly and curses a lot. Then Ml brings Mc to the city hall and they register their marriage. Then, (idk how it happened because it's been a long time) Mc and baby is now taken into a psychological (?) institution or shelter and they're monitoring his condition/relationship with Ml because it was suspicious and they believe Mc is being forced/ abused. This didn't stop Ml to sneak in and go spend his time with them.
Once they got out, Mc is more assertive and even curses at/ orders Ml. He can now match Ml's freak and does dirty talks to him. Ml shows Mc off in his work place, dotes on hime excessively, and likes how Mc became dependent on him during pregnancy. They're also still sexually active even if Mc's belly is big.
Mc gives birth and they truly become a family with Ml being overprotective of Mc and the eldest child and always teasing their 2nd child.
