On the day her daughter brings home her fiancé, Yuma Takase, Reiko blesses the couple from the bottom of her heart.

Before long, Reiko starts to feel bewildered by the emotions sprouting within her.

Creator Comment

As a mother, as a wife, and as a woman. The happiness she wants to protect and the emotions she cannot suppress. I wrote this adult forbidden romance to be poignant precisely because no one is at fault.
