my son's mother, mizuno narue, is calling on me every night.

She married her father and son family as their second wife. Her husband Kensuke was good for her, but her only son Takahiro could not open his heart and she had trouble with her head. One day, my husband Kensuke was able to leave the house for a few days on a short business trip. Azumae can not hide the tension in her life alone with Takahiro while feeling anxious. But that night, the furouma of his sleeping bedroom opened gently. And Takahiro, who began to recognize Koreyoshi as a "female", sneaked into the room.
