Sae Okumura

Age: 26

A company employee who is an expert at her work. She has known her childhood friend and now husband, Yuuto, since preschool. She had one-sided affection towards him for a long time until she confessed her feelings after graduating from university, leading to marriage. Because they had been friends for so long, they had a short sex life which resulted in her being unfulfilled sexually.

Sae is both stubborn and filled with pride. She seems abrasive towards other people but has a soft side, and despite her harsh words towards Yuuto, she eventually gives into his wishes.
