Even if that is the case, Ken is still the one in the wrong. I still feel bad for Kirara.... he loves Ken but can't say anything, but Ken kisses him and blames Kirara, that is so not right. I just want to slap Ken!
I know this happens in alot of manga but doesn't mean I have to like it... I just wanted to rant about it on this one. :D
I actually think that ken doesnt seriously blame kirara? Like he said it's your fault because kirara made him can't contain himself anymore and just went for the kiss. Seeing that kirara is shocked and confused he said "it's all your fault". I think of it not in a mean way more like a cute way since kirara is happy about it and they kissed again in the next chapter. Well it's just my interpretation, sorry if i'm wrong :3
I won't say you are wrong, that could be the case. I just got kind of annoyed about the whole thing of someone being in love with someone but sleeps with anyone that's not the one they love, and takes forever to say anything to the one they love. So I thought I would rant about it on this one. lol
I do like your way of thinking better with the whole thing. :)

WTF? Kissing him like that and than saying it's Kirara fault... How is it Kirara's fault that you never told him your feelings Ken? Going around doing what you will with every girl that walks up to you but not saying anything to the one you like... yea that's just so right of you!
Why does pretty much all manga have to have them sleeping around with everyone else but not going after the one they really love? AH, I feel bad for Kirara.
