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!
I grew up without a father, 
and I have a younger sister.
Ich bin auch ohne Vater aufgewachsen
und habe eine kleine Schwester.
Crecí sin mi padre y tengo
 una hermana menor.
Crecí sin mi padre y tengo
 una hermana pequeña.
Ma mère m’a élevée seule 
et j’ai une petite sœur.
Sono cresciuta senza padre
e ho una sorellina più piccola.
Em casa somos eu, a minha mãe e
 a minha irmã mais nova.
