y/n fall in love with jung-hyun in collage and get married too without knowing the jerk he is. After marriage he show his true colours and start sleeping around leaving y/n behind. y/n can't do anything against him because whenever she try, jung-hyun beat her up brutally. Her father in law aka Jungkook, just came back from London to expand sometime with his family. Jung-hyun is adopted and jungkook is single father. Being mafia jungkook never married.

He came back and in a week he notice his daughter in law isn't looking normal but maybe scared of his son. After looking over them closely he notice that jung-hyun stays outside almost every night and told his men's to keep eye of his son and get to know about everything.

He call y/n in his room and sit infront of her with serious yet face with pity for her

Jungkook: "y/n you shouldn't let anyone harm you dear. I'm with you. Tell me what's happening here."
