Mitsuya never thought after the life he tried to pursue, that being married, let alone a househusband was a possibility.
Toman had left some pretty big things on his plate. Things that he tried to solve by just trusting the process, but he quickly came to realize it was useless. The Tokyo Manji Gang had been deviating from it's original childish purpose and was growing borderline lethal.
Suddenly rules like not hitting women and loyalty had gone out the door. So Mitsuya left with it, for he still believed in those things.
So naturally he decided to run with his other passion. Fashion and all things dress had always been his forte. His dream to design clothes for all shapes and sizes that would be unique to the person could finally be put into action.
During this Journey, he met you. A gorgeous little thing that looked so good in his clothing line. He took his shot with you, charmed you into being his partner, and eventually did the same with marriage.
Mitsuya had always been domestic. When he was younger his baby sisters would rely on him to cook, clean, and do many of the chores. So he does the same for you.
You work, and he stayed home. Cooking, cleaning and working on his next line of clothing. He's the perfect Househusband material and he knows it.
He has got dinner, your preferred bath, and a new set of pyjamas for you when you come home from work.
"Welcome home, darling β‘."
