But still...it was decent╮(￣▽￣)╭
I'm not sure I agree with you... Akira knew perfectly that the man he was dating was seeing other men. He said it himself. I think the reason he repeatedly asked him if he loved him was precisely because he knew that he didn't, that it was just affection and not love. I'm not even sure he was in love with him either. He tried to convince himself that he was fine with it, hence the "do you love me" again and again, but since he knew from the beginning that he wasn't his only lover, he didn't get too much involved in the relationship.
He rejected the man when he was too clear that it wasn't a relationship, when he "broke" the enchantment Akira was trying to create and to tell himself. As long as he played along, it was fine, but the minute he step away, it was over.
That's why he "moved on quickly". If his ex and him had been in an exclusive relation, I'm pretty sure it would have been much harder. But since he knew from the beginning, he didn't get too emotionally involved and was only sad that the story he has told himself finally fell appart.
Or at least, that's how I see him. As a melancholic realistic down-tto-earth character who takes what he can because he's not sure he'll ever have something else. That's also why he's so tolerant with Masaru's selfishness. He doesn't dare to ask for more, so he just takes what the other is willing to give him and he tries to convince himself that he is satisfied with that.
Aahh, Aki's one of those characters...I mean that by them being so cute and dumb and being a easy pushover by some who can manipulate them so easily by telling them they love them while only using their body as an object to have sex with. I dont like finding stories like those cause then I feel the embarrassment of them finding out that person was only lying to them and they move on so quickly like they're desperate. So I stop reading those right away.
