One day during summer vacation, as Yuri's younger brother Oshimoto Yota has nothing to do, the super rich and air-headed heiress Takamiya Nasuno comes to see him!

Yota, who unwillingly becomes Nasuno's butler, gets a tour of her villa which turns out to be a very strange place...

Continuing the previous episode's story, Nasuno and Yota end up playing water polo in the pool with Kanae and her friends. However, the weather suddenly worsens and the group seeks shelter inside the villa where an unfortunate incident occurs...

I nearly passed out from dehydration. Would you like to lick my sweat?

You call this half-assed job cleaning?
