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--?!
But when he's being this stubborn, 
it always means he's hiding something.
immer wenn er so überzeugt war,
Pero siempre esconde algo
cuando es tan terco.
Pero siempre esconde algo
cuando es tan terco.
mais en général, 
quand il est si sérieux,
Ma il fatto è che quando diventa così cocciuto
è sempre perché sta nascondendo qualcosa.
Mas ele sempre está escondendo 
 algo quando é teimoso assim.
