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 think I once felt this way a long time ago.
Mir kommt es so vor, als hätte ich mich
schon mal vor einer langen Zeit so gefühlt.
Creo que una vez me sentí así.
Creo que una vez me sentí así.
J’ai vraiment 
une impression de déjà-vu.
Credo di essermi sentito
così anch'io... tanto tempo fa.
Acho que só me senti 
 assim há muito tempo.
