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...
Ren and Haruko-san are more 
like a family than we are.
Ren und Haruko-san sind halt mehr
wie eine Familie als wir.
Son más como familia que nosotros.
Son más familia que nosotros.
Après tout, Haruko est plus 
de sa famille que moi.
Il legame tra Ren e Haruko è più simile
 a quello di una famiglia, rispetto al nostro.
Ren e Haruko-san são mais 
 família do que nós somos.
