I hate him precisely for the reason you mentioned. It's not the uke's fault that he fell in love first. So why are you mentioning a reason that would make us hate him if you, as you apparently seem to think, don't want us to? T.
So, you immediately hate a person without giving him the chance to answer? Uke fell in love first, yes. However, by seme's action, it's very apparent that he have also fallen for uke. People are dense sometime and missed the smallest of gesture that may means a lot to another, and that's precisely seme. He thought his actions speaks for his lack of words Apparently, he's wrong to assume that uke understood. However, things get solved if people talk it out and listen for answer. Immediately hating someone because he's dense is just wrong. Uke didn't even wait to heard seme answer. He just say what's on his mind, cry, and ran away. It's also not the seme's fault that uke didn't wait for his answer which drag the misunderstanding. So, why hate? Chance needs to be given. Reasons needs to be heard. If seme was indeed the bastard you make him out to be, sure hate him for all you feel is right. But, from what I've seen, he's just dense, but indeed love uke too.
That escalated quick. But, I think if uke have stayed instead of running away after bursting into tears, seme may have mention he do like him too. Don't hate seme.
