I did not care for Rio story because he is a really stupid person, the whole story and scenario is really shallow and incoherent. But Haruko is great. And most people really did not get the story. Haruko a) really fell in love with big brother b) was not forced. As we saw in their first encounters he did not let people pinned him down if he didn't want to. He said himself that he allowed it as "rough game" when Masami apologized. And Haruko didn't want to have an affair with a married man. As for Masami he didn't want an affair, he was hesitant in leaving his wife because of her condition but he loved Haruko so much that he was willing to try. And when Kanako accidentally hurt him he took the blame so Kanako would not be detained in some psychiatric clinic. Ayumi is indeed a nice character but Haruko never saw him as something more of a friend

But I was "fluffy" (fat) and I lost a lot of weight for someone. I did not have to do plastic surgery, my face is good. But he kept seeing me as my old self. Neither my effort or my new looks make any difference to him. A common friend told me that it was because he knew how I was before. And he kept choosing girls that treated him like a living wallet. After many years (and many breakups since he was not especially rich) he married a "fluffy" girl.

It is admirable of you that you had the strenght to want to change yourself for someone. But the thing is, we often get attracted to something that seems so far out of reach. I know this myself. I was never ugly or overweight. I was always somehow cute, not an outsider but not a complete insider as well, like I was always somehow me and had my people here and there. My look was cute I would say. Haha. So I too was attracted once to the one who was one of the most famous dudes at school. What I learned later was, that somehow, the fact that he was someone who seemed so hopeless to get, was also what made me want him. Cause deep inside, I was not ready for a relationship. I was sad, confused, I did not know who I was what I wanted from life and was overwhelmed by life and everything I had to do before graduation. Everything was too much, so this guy was like my sunlight. He kept my mind and heart occupied with my admiration for him from afar. And then at one point, when I realised he would be gone for good, I told him I wanted to get to know him better before he went away to study. And he refused. That was me, giving up. I gave him the choice, cause I had nothing else I could to. I needed to end this, before I obsessed all my life about something that may never happen. Truth be told, after he left, I never saw him again. Although friends would tell me he would be here and there. As if a line that connected us was cut by him that day. we never saw each other again. Just once. Four years later. I was me. I was stronger, liberated, on my way to fully achieve the freedome I always longed for. Freedome from the voices of the society and my past, just me. Me who lives like I want to live and bends to the rules that I want to bend to. I was just on my way to go and get my backpack for my first solo journey out into the world. Super hyped, but stressed as well. Cause the me four years ago, would have never ever dreamed of being that strong. And that is when I saw him. I did not recognize him right away. He looked so different to me. And sure thing, when I just did my thing (looking for my phone in my purse) and looked up again the second it irked me who he could be I saw him running away from me haha. Why, I never will know. But, I laughed. He was so shining in my memory. But that day I realized, I made him shine like that in my own eyes. I did not need him anymore. I learned new feelings through my love for him. I sure did change. I did the same mistake 2 more times. But through those I learned other things and did different stuff. But the last one I realized much much faster, that it was karma telling me to get my shit together and no longer use this fucked up thing to forget about reality. That I was strong enough to face life alone and did not need a shining prince to guide me. So I told the third dude that I liked him, but did not want anything like that. And left haha. I traveled the world, I have people who look up to me now, I am freaking happy and I realized how strong I am and that I can stand on my own two feet and am my own warriour. I will one day find another strong warriour and walk onto the battlefield back to back with him. But I will no longer run in the shadows of some dude and keep low for his sake hoping he would guide my hand, because I was too scared to stand strong on my own in fear of being lonely. :)

Oh by the way. I met him there, after I decided to stop my want for the third dude. It was like as if a circle was closing that day I then saw him there at the station. So girl/boy. Be strong. Be you. Live your life and learn from the past. Accept your feelings and your fears and then move on with more wisdome to be a better you tomorrow. :)
Why good hearted and innocent people became devils?
It was explained.
The first devil was a natural "seducer" (people liked him, the seme liked him, he didn't bother doing anything about it - although he's totally oblivious, so yeeah, natural) so he fit the job description.
The second one has a deep grudge against his family that he can't become an angel.
