i agree. they should have stated exactly what their relationship was before the separated for the 6 years, defining it, and letting each other know if it was ok to see other people. mi-kun must not have been that much in love, cos if he loved him as much as he always said he did, then he would've kept it in his pants.kei-chan deserves better...but hey, damn mangas always gotta hae conflict. why can't the stories be as fluffy as katekyo? :)
I totally agree with you .I mean there is something called far distance love, and even if he wouldn't move to Tokyo it doesn't mean you cant be a couple.and even more than this;far distance love isn't an excuse for cheating.And if Mii-kun couldn't bring the topic "hey can we have an open relationship"then he just had to endure till the moment they can make sex together.And if he wasn't sure about Kei-chan's feelings to him,he could just talk to him even if it's hard to him to ask something like that .I know it was hard for him to ask him to come to Tokyo,cause yes,communication with the one you love cant be always an easy thing, but fucking with someone else and after that trying to ask the one you love to move to your place is an ugly thing to do.
I don't know what i would've done in this situation,but one thing I do know-got sent an angel to Mii-kun .Not everyone can be as undernstanding as Kei -chan.For example-I cant.
and if it's the case ,then maybe he wasn't going to ask him to move to Tokyo but going to break up with him.And maybe none one of them paid too much attention to this cheating cause for them it wasn't a cheating.I mean one of them wasn't sure about his own feeling, and the other one was sure his love is one side love

I thought I was the only one who felt that way. Everybody else is singing praises about love and fluffiness, and I agree it is there, but the sex outside of a relationship was a dark shadow in the story for me. Haters can hate me. I think that if they were going to be apart for six years, and Mii-kun wanted to fuck around with other people because it's a "physical need," then they shouldn't say that they are in a relationship and just call it friends until they can be together for real. Kei-chan didn't sleep around, or at least there was no indication of it. He's a man too, with physical needs, so why was HE faithful for six years? Is it only gay men? I don't think so. Kei-chan should fuck a couple guys and see how Mii-kun feels about it. Okay, that last part was just the vengeful me coming out. Another thing that bothers me is when Mii-kuns friends put Kei-chan down - "he's plain, he's boring, I don't get what you see in him," that kind of shit. I've seen it in other manga and it pisses me off.
