So Yamato here is the new head of a well-known Dreamer family line who is occasionally employing their skeevy dad. So that's how he would end up housing them in his big ass and mostly empty property. He's hard to get along with because he's unsocialized and kind of a prick, but not completely unreasonable- basically as long as they don't cause him trouble or embarrass the family by proxy he won't ask much of them- though soon as he learns Ayako is a Dreamer (and eventually Meow, probably) he will have much higher expectations of excellence. Cuz he's just Like That. What do you mean not everyone wants to be on the grind 24/7???
