So, I'm trying to understand why the description of the character of Hananoi is so harsh. Hananoi is a victim of parental abandonment and childhood trauma. He has no siblings, but his parents are obsessed with children in other countries. He has dozens of photos of them with children in poorer countries, but none of them with himself. As a consequence, he has deep-seated attachment issues. However, because of his appearance, he's had more interpersonal relationships with members of the opposite sex. But he's ill-equipped to cope with them, because of his emotional isolation. I think it's a bit noble he keeps trying after so much rejection. Hananoi remembers Hotaru as a kind and caring childhood friend -- and he's not wrong. Meanwhile, the Hotaru character seems emotionally repressed and underdeveloped. She just seems to be an adjunct to other people's lives: Her friends and her family, like a much younger child. She has no relationship with or awareness of her own sexuality. While the same age as Hananoi, she states she's avoidant of males and dating. That is, similarly, because of childhood trauma. Hananoi is attempting to guide Hotaru to grow to be able to have a mature emotional relationship with a male, himself. And, he seems kind and quite restrained in light of his desperate neediness. Neither of these characters is entirely well-adjusted. And they actually have surprisingly similar and complimentary emotional needs. I think Hananoi is right that they're well-matched. They complement one another, in both their strengths and weaknesses. The relationship ultimately supports each character's emotional growth. Both of them were deeply lonely. Hotaru didn't know she was lonely, because she didn't know what romantic love was. It was his task to teach her, and he did. He thinks she is literally his soulmate. And he's right.
So, I just don't get why he's being trashed. It seems as though those who are criticizing him are dealing with their own issues and values and projecting them onto the characters. Yes, he's obsessive. But he's obsessed with and appreciative of Hotaru's inner beauty. He's not hurting her; she grows immeasurably through her relationship with Hananoi. I love these two characters and their relationship, because they're very finely drawn and not cardboard cut outs of idealized lovers or a hero and heroine. Yes, they're flawed, but aren't we all? I'm loathe to criticize others' relationships, especially when they're filling their emotional needs. I think that, after not having love throughout his life, he's found his soulmate, and he knows it. More power to the brother. And more power to Hotaru. She's found a brilliant, gorgeous dude who worships her for who she is. So, leave my dude alone.
