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 you really can't see me as more 
than just a brother, tell me.
Falls du mich doch nur als
normalen Bruder ansehen kannst,
Si de verdad no me ves más
que como un hermano, dímelo.
Si de verdad solo me ves 
como un hermano, dímelo.
Donc tu me vois bien 
juste comme ton petit frère.
Se davvero non riesci a vedermi come niente di più
 che un fratello, dimmelo chiaramente.
Se você realmente não consegue me ver 
 como mais que um irmão, me diga.
