I don't need it to be that fluffy, but do they ever care for each other? Not as in embracing each other or confessing, but from where I read up to last time, they didn't really care at all about each other, they were basically just master/slave without any sort of a deeper relationship. Like do they get jealous, are they protective, does it ever break out of a one-sided forceful relationship? I don't imagine there being any declaration of "I love you" from either side, but does the uke (or seme) ever stop completely despising the other?

I think that here's a hint of what you can expect about them and their "twisted" care for each other. I do believe Karino has always been felt atracted to Azusa and what he did it was his way to monopolize him, to take him all for himself. I don't expect any love declarations either because it's not (till now) what this story is about, I believe it's a interesting view of certain kind of relationship, certain kind of love.
I think it's more like going forward and backward with them. In that chapter it seemed that things were getting to a next level but the next chapter Karino kind of rejected him (Azusa went to his house to give something Kuze was sending to Karino and he told him practically fuck off, I don't want you here). And then Azusa is plotting revenge but things aren't going his way (Karino is always winning)... but anyway, I think you should give a shot with the story because no matter what could happen later, it's interesting their dynamic. I think that in some point, the story is going to turn to "romantic" (in its possible kind of way).

I read this manga quite a long time ago, but since recently I lost touch with it and didn't keep up with the updates. Does this manga hint at romance at all? Some people don't need romance, and thats fine, I just want to know this for personal reasons.
