You're right that there's plenty of blame on both sides, and I'm glad that Shingo is finally beginning to realize some of his mistakes. But I would like to point out that it was Keiichi who first suggested that Shingo didn't love and trust him, because of the scent thing. Also what I thought Shingo said was with Keichi gone he would go back to old habits, and rather than cheat, break up. Of course they are both being emotionally dishonest,which is the problem.

I just want to tell people that want to see Keichi burning in hell to go read again chapter 7. Shingo really say cruel things to him like he maybe never loved Keichi, he never trust him and if he go to america he would cheat on him with the first man he found on the street. Do you be happy hearing those things said by the one you truly love ?
So now, he come to see Keichi on America. Ok, that's great but if I were Keichi, after I was told all these mean things, I won't show happiness yet. I will protect myself even if I hurt the other one. The best form of defence is attack.
