I agree with you.
And I don't want everyone to be too hard on Akira because there are people who are just not strong enough and get overwhelmed with stress and anxiety. I'm that kind of person too, I get freaked out about every little thing and get really really scared sometimes thinking too much. Like really scared how my life is going to be.
I think he had to go through that to really enjoy his time with Yuuki again.
And Yuuki was so forgiving and understanding.
The point here is that Yukki feelings are not taken in consideration at all.Sure, Akira will be more convinced but Yukii on the contrary will be allways unsure and thinking when will be thrown away again. But Akira will be ok thats for sure.
Well, those kind of feelings will, if not dissolve, be dulled by time (unless Akira becomes a true asshole and leaves him again). Akira has to feel responsible for the effects of what he did so if we assume that they have a happy ending, the conflict you said has got to be solved somewhere along the way.
Yeah, well, anyway, the one waiting is Yukii and the relationship is wounded, it wont be the same anymore, at least thats how would be in rl but this is a manga so the realistic part is avoided here.
The plotline is so fresh. Akira was selfish as fuck but to be honest, that's human nature and this happens to almost everyone. What's beautiful about this is that after Akira's mistake, their bond will be stronger and he would be more convinced that Yuuki is the cornerstone of his life. I agree that the development was kinda rushed though :)
