I saw the tags and was hoping this would end up being fun and fluffy, but I guess I was unfamiliar with the author.
Weirdly enough, this is exactly the opposite of my experience. I expected much worse form the tags, and despite what a lot of other commenters are saying, I have so far seen no indication whatsoever that it won't turn out just as fun and fluffy as the first chapter suggested. As for the author, they have enough variety in their works that it could go either way, and even if they didn't, surprises are always possible, just look at Usui Shio.
