What bothered me most is that if Shingo had been made aware, it would have awful. I know that they were not together but with Shingo's abandonment issues that he was aware of? Why was he (Keiichi) such a selfish dumbass in this situation? Argh...It irritates me to no end. And I'm certain that Jin and Ei were aware of the entire situation. And I love how they were the ones who helped diffuse things.
Keiichi is this kind of seme; possessive, overbearing, egotistical sexy af type we (the fans) all have this love/hate reaction to. Yes, he is wrong in a lot of ways but he gets things right sometimes and we forgive him for some of the bad. If you think about all the issues both of them had and overcame it's a wonder they are even together.
Damn, Angelo just keeps appearing, doesn't he? Ei sure knows how to tease Jin. I just love how possessive he gets. ლ(´ڡ`ლ)
