南雲 惠子

Former homeroom teacher of the main character. Her husband passed away 10 years ago. Since then, she has forgotten that she is a woman and raised her daughter, Sae, single-handedly.

During that time, she had never had any physical relations with a man, and even after her husband's death, she still wears a ring on her left hand.

However, when the protagonist comes on to her in a way that tickles her maternal instincts, her suppressed sexual desire gradually melts away, even though she denies it in her own words.

After the birth of her daughter, Sae, she has developed a peculiar condition that causes her breast milk to come out when she is aroused, and she often milks herself without being seen.
