I can understand where everyone is coming from when they write a review about this manga. I wouldn't call it terrible, it's just tasteless. The art was good and the story was decent, but what got me was the characters.
I wasn't too impressed to be honest. The characters kind of annoyed me. Every single character in this manga, especially the heroine.
I think that is what everyone can agree on. The story would've been been better if the characters were better. But don't get me wrong, I'm not saying this story is the worst manga ever made in history (To some people it might be). I'm just saying that it could've been better.
Either way, I still found it enjoyable to read to kill time. There are better mangas than this, but then again, this manga is a lot better than others too. So instead of saying the "worst" or the "best", let's leave it at "decently good".
