大島 雄貴

He is 30 years old with a dull appearance.

Insidious and obsessive. He is a little bit intuitive. Although he dreams of a normal love life, he is still an amateur virgin due to his mean personality. He has a complex about the fact that he has never had a girlfriend, let alone getting married.

The husbands of both Miyako and Honoka are Yuuki's older brothers. Both of them are working and are active in their respective fields. Yuki, who still does not have a regular job, has no choice but to spend his time as a manager of the condominium owned by his parents.

The older brothers also live in the same condominium because it does not cost them rent and they do not live together.
