People getting offended over the tags amuse me. Nobody is commenting on the fact that the author just managed to contrive a major misunderstanding into existence, when both of the parties who know the true circumstances are afflicted with a fantastic illness that literally forces them to yell out the truth?
And neither of the two have the werewithal to even send Sayoi a text saying "We're not dating, it was a big misunderstanding that we were about to explain before the author blew up the world around us because she was about to run out of conflict and panicked"? I find that hard to believe. If the next chapter begins with anything but Sayoi saying to Hiyama "Ok so my sister explained how it was a big misunderstanding and I apologize for getting you involved in all those rumors" then there'll be cause for complaint.
Here I go, trying to discuss the actual manga and enjoy it on its own merits. Fuck me, right?
