What's the relationship between miyo and asaya's mother?
I'm very confused with that twisted family LMAO
Is the current guy we saw Asaya's dad? Or step dad? Cause they mentioned she was divorced....so they're divorced and he's still whipped? And then she kept mentioning an ex and it looked like they were talking about the Kou/Ken's dad... but then Kou said him and ayaka are same age and Ken and Asaya are the same age....did their dad cheat or what? LMAO
