It's Ren's first summer vacation in Japan. The landlord of the apartment he and Haru once lived in hires him to clean one of his apartment units. Haru becomes unbearably curious when Ren refuses to tell him why he got a part time job. Kiyoka suspects Kiri, Ren's female classmate who has been coming over with her dog to hang out, but...? And while this is happening, an unknown man suddenly approaches Ren--?!

Eu sou o único que se 
 importa com essas coisas.
