And finally I have made it to the end of this drama. I really should have finished up months ago as I did enjoy it.
In the letter Origuchi tells Hiro that she loves him and thanks him for having known him in her life.
Maruo has come to peace over what happened with him and Hiro those years ago and goes so far to tell Hiro that it would be okay for him to visit him.
Mizuho confronts Hikaru about knowing about Origuchi but doing nothing and for waiting so long to give Hiro the letter. Hikaru just acts in his usual aloof manner. As Hikaru walks off Mizuho finally tells him that she does not regret the relationship they had and she is willing to accept him for who he is without getting into his past because she believes in him and the fact that she will see him again. She hugs him then they part to go their separate ways.
I think the only part of the end that I did not care so much about is Mizuho and Hikaru. Probably because Hikaru does not seem to have changed throughout everything. But I guess that is to be expected as it really was Mizuho's journey but Hikaru's future seems rather bleak as he still has no direction and has not really done anything to change himself. But who knows, perhaps it is Mizuho's change that will make him want to do the same now or something. And I am glad they did not end up together immediately for the "perfect" happy ending as again, I don't think Hikaru is at a place at the end that he could give Mizuho the kind of relationship she wants from him.
Overall though I enjoyed this drama and it renewed my faith in this drama block after the lackluster Sprout.
