Shingo broke up with Keiichi, how is he supposed to react? "omg Shingo!! I can't believe you are here, can we please get back together even though you were the one who left me?"???

Maybe he could say hello and wait to see why Shingo came instead of treating Shingo like a stranger (the same way he treated Shingo around Angelo before they broke up http://iweb6.mangapicgallery.com/r/newpiclink/kuroneko_kareshi_no_afurekata/3/1a7f1265e9394f46529ec41d98f518a5.png). They both have faults, but Keiichi is still acting to cover up instead of to share information.

Those are two different times with different motives the first one was because Keiichi didn't want to draw Angelo's attention to Shingo (tbh Angelo is annoying af so it's for the better) and the one on this episode is either because he is pissed (which he has every right to imo) or because he is protecting himself

you've got a point there, but then, why bother asking Rio to say "I like Shingo the most" everyday if he wanted to play the cold guy afterwards?? Well anyway, I don't get both of them, I mean, why Kagami lied to Shingo about his continous nightly activities with the other guy and why is Shingo still carrying on his insecurities? aaahhh sensei is really playing with our emotions!

It may have some different circumstances, but the types of behavior is the same--he is pretending Shingo is a stranger instead of being willing to talk about whatever t is that is going on. The roots of the problem existed before the breakup. While both are at fault, if Keiichi's repeated declarations of love mean anything, it should mean he would talk in such situations and let Shingo know all the things he didn't before and apologize for making a decision to leave the country on his own without talking to Shingo. Then Shingo should apologize for giving up too soon and Shingo should admit his feelings too. But this problem all started with Angelo--and with Keichii not talking to Shingo about whatever it is that is going on with Angelo. I also need to know what the truth is about the scent, because I still think there is more going on there (and it is important).

I agree with you on the note that Keichi started this whole mess by not telling Shingo about Angelou, and that its both their faults because no one is communicating with the other. However, I feel that Keichi has a right to feel upset that Shingo just broke up with him out of the blue like that. Anyone would, really ╮( ̄▽ ̄)╭

yeah but that was waaayy too cruel, I mean, the guy says "do you need something?" so casually like talking to a stranger when he should realize that the other guy travelled thousand of kms (many hours) for an important reason. At least, he should have said something like "Shingo, what brings you here?" or "hello Shingo, what's up?" something a little less cold.
it's okey that Keiichi is angry because Shingo just cut off the relationship all of a sudden, but he shouldn't behave like a scorned woman either.

I thin Keiichi is right to be upset, but I don't think it was out of the blue. Keiichi must have known that not coming home night after night, refusing to kiss Shingo and then Shingo telling him there was no scent means something. And how did Keiichi really expect Shingo to take the sudden news that he was going to be abandoned again? Even if Keiichi didn't break up, he announced he was leaving for up to a year. They haven't been together more than year, right? What did Keiichi think?
I think everyone's forgetting that Keichi was hurt too...
Like, Shingo is the one that's been deciding everything. Keichi isn't just some emotionless doll that you can just drop on a whim, in anyone's case, I think Keichi is more relatable here...
