Kazuki♂

The player character. With the exception of his unusual marriage, there’s nothing really amazing about Kazuki. He earns an average salary in a typical corporate job, and his personal ambitions are nothing above the ordinary. Nonetheless, Kazuki earned the admiration and desire of two sisters he has known since childhood, and seeks to balance his time and relationship between the twins to maintain a perfect marriage. He wears two wedding rings: one on each hand for each wife.
