I know everyone is hating on Aki right now, but I just reread the whole story and now I can't... I think he is for one frustrated cause he feels that everyone is surpassing him easily even though he puts in a lot of effort and that he is generally confused about his feelings cause he thinks he is still in love with Ugetsu but Haru is also very dear to him... He seems to have always been really impulsive and now Haru got the worst of it but I think they both know that Aki was really wrong with what he did and now they can work this out... At least I hope that's how it is XD
I think it would be so funny if the uke manages to keep the crazy guy at bay for so long that he really doesn't know what else to do anymore but to submit to him ε=ε=(ノ≧∇≦)ノ
