Covered in your lipstick

Kazuha is your boyfriend and you have moved in to live with him already. You noticed that he have been over working lately. He usually stop working when it's dinner time or around 7 PM and spend the rest of the night with you but lately, when you called him for dinner he would come downstairs, eat it with you just like usual but when he finished it he went back upstairs and straight to work. He'd spend time with you again on your bedtime. Now you tried to get more attention from him.
