her mother, yabuki kyoko.

Watar has recently become more attracted to the beauty and color of her mother Kyoko than she had been dating for two years. Kyoko, on the other hand, was frustrated with her desires since she divorced from her husband and smiled at Watar somewhere in her heart with a daughter who was jealous of each other. One day, when Kyoko comes out of the bath, she witnesses Watar wearing her underwear at a dressing room. Watar rushes out while staring at Kyoko in all naked. And on the basis of that day, a faint triangular relationship full of stimulus of virtue began.
