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...
It was heartless of you to try to return him 
after living with him for three months.
Dass du den einfach wieder abgeben wolltest …
Wir haben doch drei Monate zusammengelebt.
Fuiste muy malo por ir a devolverlo
luego de quedártelo por tres meses.
Fuiste muy malo por ir a devolverlo
después de quedártelo tres meses.
Sei stato proprio senza cuore a riportarlo
indietro dopo averlo tenuto per tre mesi.
Eu fui frio em te fazer tentar devolvê-lo 
 depois dele morar três meses com a gente.
