At the beginning i thought that so was a bastard and selfish person because he kept lying to kou. Despite that, after reading the while manga i understood kou's feeling about ao..
I think that if all this happeed to me i would've gone with ao, not because i pitied him but because eh had bene with me for so many years, bearing all of my cheating and stuff.
I also liked mikuni a bit but in the end i think that when he was young he should've tried to call kou and not to wait for him (in love you have to act!). He just tried to steal another person's lover just for giĆ own satisfaction, even before discovering the truth.
Finally, i think this is a really good manga, also because the art is really good and the plot is interesting. Obviously, it's not the kind of ending that eversione agreeds on but well, this happens with every story ;)
*spoiler*
Why didn't jesus stop all of this chaos from the beginning? In the end he just went "YEAH i'll fix it all!" When he could've done it earlier..
I really loved this story so this is not a complain. I just don't really get the ending
