Aizin Shikkaku

Kazunade is a plain office worker at a bridal company.
She is a shy and self-confident woman, but one day she meets Akiyama, a man she met by chance, who gradually changes her.
She thought she would never see him again, but when she meets him again as her boss at her own company, her heart is drawn to him more and more.
However, Akiyama is a married man...? An unforgivable erotic story spun in an office.
