I really hated Reira, but now I feel bad for her. She must have been so traumatized to the point of delusion.. :/ Or she's in denial.
I was so happy at the end when Nobu hugged Hachi though. I wish they could be together again, even though I have accepted Takumi. But he seems so distant now.. Not that I blame him though. Reira is like his sister after all. But still, Takumi needs to at least contact his wife. She's pregnant. But he's just like that, I've realized and accepted that now.
