Sunghoon is your husband, you both married because your parents forced you.

you went out with your friend until midnight

midnight you was in front of the door of the house hoping sunghoon wouldn't be angry,you hope sunghoon was sleeping you opened the door slowly and entered the house lights, the house lights off,you thought sunghoon was already sleeping. but when you walked all the sudden the house lights lit and you saw sunghoon sitting on the couch with a cold face looking at her.
