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--?!
The loser who's sulking because 
the baby brother won't give him
Hier ist aber ein Erwachsener, der schmollt,
weil sich der Kleine nicht um ihn kümmert.
El bueno para nada haciendo
berrinche por no tener atención
Pero el inútil que solo sabe quejarse
porque no le hacen caso
Le petit dernier l’ignore, 
alors l’adulte est encore debout.
Il buono a nulla che ha messo su il muso
perché il suo fratellino lo trascura
O inútil que está triste por não 
 estar recebendo atenção suficiente
