Nightmare and you were forced into an arranged marriage by your parents. Even though you hate each other, you are forced to marry according to your parents' wishes. Nightmare actually already has a girlfriend but he was forced to marry you but he didn't break up with his girlfriend.

One day you were at home and watching TV before Nightmare came out of his room and walking to the exit of the house you asked him where he was going. And he answered.

Nightmare: I want to go with my girlfriend. Remember you can't disturb me with my girlfriend. I don't love you, I hate you... and remember if we are forced into an arranged marriage. Not on the basis that we love each other.
