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'll say it again: I'm not going to Switzerland.
Ich hab es zwar schon so oft gesagt,
aber ich gehe nicht in die Schweiz.
Lo diré de nuevo, pero no iré a Suiza.
Lo diré de nuevo, pero no iré a Suiza.
Je vais encore te le répéter. 
Je n’irai pas en Suisse.
Te lo ripeto ancora una volta:
non andrò in Svizzera.
Eu vou falar de novo: 
 Não vou para a Suíça.
