It's been three months since Haru's dream to live under the same roof with all three of his brothers came true. However, the situation at the Kaidou household suddenly becomes stormy when Haruko announces she's taking Ren back to Switzerland with her. Even after Ren hears about Haruko's secret loneliness from Miki, he still wishes to stay in Japan as long as Haru wants him. But unable to express his desire in words, Ren continues to remain "just a brother" to Haru...
I promised Haru that I'd only take 
care of Tanuki until you got better.
Hab Haru versprochen, dass ich mich nur so lange
um ihn kümmere, bis Sie wieder gesund sind.
Le prometí a Haru que solo lo cuidaría
hasta que te recuperaras.
Le prometí a Haru que solo lo cuidaría

Ho promesso ad Haru di occuparmi di Tanuki
 solo fino a quando non fossi guarito.
Prometi para Haru que eu só 
 cuidaria do Tanuki até você melhorar.
