"the fact that Mii-kun kept claiming he's been in love with Kei-chan all those times "
sorry, I don't remember kei chan saying that until he decided go to live to Tokio, maybe I skip that.
I don't take what Mi chan did as cheating because take place before that moment. Kei chan maintain it in the air all those years what he feels really for him, and until the very late moment he is not sure if he wants Mi kun or not, he doesnt communicate until he feel sure, is very naive to think he was going to wait when you are sending nothing but signs of friendship. I feel that Mi kun didnt confront him all that time because he doesnt want to lose his last hopes. But its natural for Kei chan being jealous right now when he is inloved although he hasnt many right to being mad.
I think the two of them are cowards but this make possible for them to be together in the future cause othewise Kei chan would be sincer about his feelings and they would break all ties..
I salute that guy for being able to brush off Mii-kun's cheating incident(s) and allowing another guy (Haru-kun) to be all over him despite knowing their history... I understand how Mii-kun was lonely and he was losing hope of ever being with Kei-chan the way he wanted. After all, when they separated, Kei-chan wasn't really in love with him and just accepted his confession because he couldn't refuse. We even learnt that when they were dating in high school, Kei-chan practically shut down the possibility of them having sex and declared that even though they're dating, there would hardly be any changes in their relationship (so they were more like BFFs who kiss each other).
Well, in Kei-chan's POV, of course he got jealous, but he didn't want to dwell on it because he felt that he's to blame for not being with Mii-kun all those years. I guess he just reminds himself of all the reasons why he loves Mii-kun everytime he feels insecure, so he can forgive those acts. I think that's amazing because it'd be hard for me personally.
Don't get me wrong though. I super like how adorable Mii-kun and Kei-chan are together. They're practically inseparable. I just hope that since they're lovey dovey now, Mii-kun should keep his guard up against others instead of letting them do what they want and allowing his libido to take over.. Yeah, like those instances with Haru-kun. Thank goodness his uke-san (forgot the name) finally reprimanded him. I think they are a good pair on their own. (I'm not prepared for a foursome when mutual love is involved. If they weren't in a relationship and really just fooling around casually, I'd welcome that though!)
Oh, and I just remembered... Mii-kun seemed to be prepared to be an uke to Kiyomi-san before, didn't he? I think he really wanted to be spoiled by an adult and maybe he was unconsciously avoiding being an uke because it was meant for Kiyomi-san. He was special to him because he was a great support in terms of his sexuality after all.. Remember the face he made when he's with Kiyomi-san? He totally looked like he wanted to receive. (Though Mii-kun considered he could maybe allow Kei-chan to top him too, he hasn't really decided until the others teased him about Kei-chan losing his virginity to another.)
So yeah, I guess it is a consolation for me to accept Mii-kun's affair(s) when he gave up his anal virginity to Kei-chan. I can at least preserve the memory that they had each other's firsts and focus on their lovey dovey relationship NOW instead of Mii-kun's PAST cheating record(s).
ps. Even if their "relationship" was vague when they separated, the fact that Mii-kun kept claiming he's been in love with Kei-chan all those times made me feel betrayed when he fooled around. He didn't even intend to reveal it if Kei-chan didn't confront him.. I disliked who he WAS but I really like him now. He's just can't get enough of Kei-chan.
Oh well, past is past. But that's why I want to know, how to be Kei-chan? I want to know how to stay positive and be lovey dovey without being overcome with jealousy... (๑•ㅂ•)و✧
