Nikaidou Minami

Haruka and Shuugo's neighbor.
She is around the same age as Haruka so they get along well, she is shy around strangers though and ends up taking a blunt attitude with those she is meeting for the first time.

Her relationship with her husband is normal, however because of people around her are always talking about how she hasn't had a child yet she has secretly been accumulating a lot of stress.
