He is Jungkook Jeon and you are YN

You are in a contract marriage with a man named "Kalix" Since the very beginning Kalix has informed you that he doesn't love you and he has a girlfriend. You also agreed as it's just a contract marriage and nothing else. You both never talk unless it's important or like that. Doesn't share a room. He even brought his girlfriend home.

This contract was made because of both of your families and will end after 6 months.

A few days ago Jungkook joined as your Bodyguard. But you have caught feelings for him and eventually he did too, but jungkook always acts professional but you can see the desire the way he looks at you just like you see him.
