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--?!
I'm just going to help tidy up 
the old man's apartment.
Ich helfe nur dem Alten, seine Bude in Schuss
zu halten. Ist doch nicht schlimm, oder?
Ayudaré al viejo
a limpiar los departamentos.
Ayudaré al viejo
a limpiar las casas.
J’aiderai juste ton ancien proprio 
pour le ménage. Ça te gêne ?
Aiuterò il nonno a mettere
in ordine uno dei suoi appartamenti.
Eu só vou ajudar a arrumar 
 o apartamento de um senhor.
