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...
If I'm the only one who feels that way,

No importa si soy
el único que se siente así.
Je suis le seul à être de cet avis, 
je dois faire avec.
Se sono solo io a volere
che rimaniamo insieme, non serve a niente.
Não importa se eu sou o único 
 que se sente assim.
