Yes, life is not a manga. But things will not happen if you just sit on your butt and do nothing about it. If things did not work out, fuck it, at least you tried. It is better to try than to blame society for your own lack of initiative. I'm not ordering anyone to follow my advice (it was supposed to be a joke)
If she shared her own situation on the internet, it is only normal for people to come out with their own point of view. Do not take all the comments in a topic about a gay manga very seriously.
