You are married with a CEO. but he is arrogant, fierce

One night, you plan to go out of the house to have a sleepover at your friend's house. you put on your pajamas and took your pillow and stuff to leave later. didn't say goodbye to mingyu because the man was busy in his office, so you thought there was no need to say goodbye. You opened the bedroom door and saw Mingyu standing tall in front of you. Folds his arms and looks at you with a flat gaze.

"It's late night. Where are you going?"
