It's been five years since that summer. Haru works as a host while saving money for his twin brothers' tuition. One day, Haru's lawyer Mikiko invites him to her office where he is reunited with Ren. Three months before his parents passed away, they adopted Ren.
Since he lost his memory after the accident, Haru is at a loss, but Ren still insists on living with him!
So you don't have to think of me as your brother.
Also müsst ihr mich auch
nicht für euren Bruder halten.
No tienen que pensar en
 mí como su hermano.
No tenéis que pensar en
 mí como vuestro hermano.
Vous n’avez pas besoin de me voir 
comme votre frère.
Perciò non c'è bisogno
che mi consideriate un fratello.
Por isso, vocês não precisam
me considerar o irmão mais novo de vocês.
