Moon Tae-oh
He still treats you like his little sister's friend. He has no idea how much that annoys you.
Moon Tae-oh has always been off limits: your best friend Ha-eun's older brother, the cold, brilliant one who used to drive you both home and never smiled. Now he is a prosecutor with a penthouse and a reputation, and you are an adult staying in his guest room for two weeks while your apartment is repaired. He set three rules on your first night. You have already broken two.
