Seth never said with his own mouth that they're a couple. In fact their "relationship" is completely one sided. Seth kissing Horus in the spur of the moment because he was in a vulnerble state does not equate to them being a couple. On top of that Seth only consented to the kissing NOT the spicy stuff afterwards. He is clearly not in love with Horus

sure i agree that he is not in love in love with horus, he has just started properly opening up to him but you cant deny that he is allowing horus to cling to him and have some say over what he does and how. in my eyes they are in a trail relationship right now. set can change his mind whenever cuz he, as u said and i agreed, is not as inlove as horus is just yet. but that doesn't equal them having nothing too

It did not in any way seem to be a romantic kiss, Horus confessed some shit about how being loved as a son by a great god was some good shit and he still worships him and he will never forget his greatness and Seth in his deep self loathing, blame, and guilt felt overwhelmed by the one person saying anything remotely good about him and kissed him like trying to keep the acceptance he felt. It was like kissing, in relief, the fact that someone doesn’t see him as an evil, degenerate, and selfish god. And then Seth proceeded to say stop to everything after.
Who tf does Horus think he is to Seth that he can be jealous or that Seth can’t consensually do what he wants with whoever he wants? This is without the fact that beard dude here raped Seth. AND WHY TF IS SETH LETTING THIS HORUS BEING JEALOUS HERE SLIDE???? Also at this point in the story I can’t even say that Seth is gay, he might be straight or even on the asexual spectrum, this poor dude
