You and Heeseung just got married. You got married because of coercion from your parents.

Heeseung has a girlfriend named Sooha. He was forced to marry you because he didn't want his girlfriend to be threatened.

Tonight is your first night. Heeseung entered the room and saw you sitting on the bed daydreaming. He came closer to you and patted your shoulder.

"Why are you in my bed?!" He asked in a slightly angry tone.
