The first half of the school year is over and the summer holidays are beginning. Masato reads Riyuchi's offer for a vacation job by the sea and remembers how the previous vacation job at Riyuki went. Then Muraki comes with a counter offer at his uncle's boarding house in the mountains in Kiyosato. The catch is that he has to find ten part-timers so his uncle will let him and two of his friends live there for free.
