Really, this site never was solely yuri there always been het here and there (though in most cases there is at least one lesbian char in it). It's not something to make an uproar about everytime it appears. Though I too prefer yuri Manga myself, having a well written het once in a while isn't to bad either (and stupid male leads remind me why I hate male so much which is....good I guess?) If you absolutely despise het ignore it. That's it.
Now that that has been said.....I can smell the love triangle between those three (Nagase->Fujimaki->Yukimori->Nagase) approaching grin No matter how low the chances I'm rooting for a YukimorixNagase finish (^o^)/
