I love author works because they are full of angst and twisted, and I get it; they are not for everybody. But it doesn't mean you will abuse the author here. Drop it and move on if you don't like it. Ironically, they are themselves making the comment section toxic. If they have guts, then purchase just one official chapter from an official site and leave whatever you feel about the author there; maybe your words will have some value then. And someone even said that it was "shitty art"??? The story can be bad, but the art??? Excuse me??? Maybe that person needs goggles.
P.S. My rant was not towards anyone particular, but rather an accumulation of toxicity that I have been witnessing in the comment section. If you don't like something, leave constructive criticism rather than abuse, and you don't need to get into arguments with people who love it. There will never be a fruitful outcome from the argument.
Atleast Sebastian should get a better ending. I have given up on others. So I don't care for other characters anymore. I'm just here to cheer for Sebastian. ლ(´ڡ`ლ)
