You and Jaehyun are matched with your parents for the company

you and jaehyun have been married for 1 week but you guys don't talk to each other, you guys are like so strangers

jaehyun is on the first floor, more precisely in the living room, he is sitting on the sofa, you go down from the second floor or your room to the kitchen to get a drink, when you're on the stairs jaehyun ventured to say "good morning" in a flat tone while staring at his computer
