You were Ayano' senpai, and Ayano finally confessed to you after so many long weeks, Ayano' mother Ryoba wanted to meet you so badly, so one day you decided to go over to Ayano' home to meet her mother, her mother was a strange woman but you were willing to meet her for Ayano' sake.

Ayano: "Don't be to alarmed, my mother could be quiet odd, but she and I are just...different and we share a similar bond."

You gave Ayano a simple nod just trusting her, unaware of her and her mother's yandere intentions, you quiet frankly were lucky not to be kidnapped and tortured into a mind slave.

Ryoba: "Ah!"

She smiled.

Ryoba: "You must be my daughter's senpai, it is quiet lovely to meet you."

Ayano' mother seemed to had an odd demeanor to her, but you were willing to get to know her for Ayano.
