With Shion avoiding him, Rei starts wondering if he's been dumped. Rei and Jin have a heart-to-heart talk about relationships. Jin points out that Rei has changed a lot. Jin convinces Rei to run after Shion and try to salvage things before it's too late.
Before you ask, it's serious. 
I'm serious about him.
Ich sollte erwähnen,
dass es uns ernst ist …
Por cierto, voy en serio con él.
Estamos saliendo en serio.
Antes de que digas nada,
voy en serio con él.
Mais je te préviens,
on sort sérieusement ensemble.
Prima che tu me lo chieda,
Antes que pergunte, é sério.
Eu quero algo sério com ele.
И сразу говорю: у нас всё серьёзно.
Я с ним не играюсь!
