First off... THE ART. THE ART IS SUPER HOLY LIKE I MEAN IT'S SO PRETTY HOW IS IT THAT IZAWA REI HAS NOT HAD AN ARTBOOK RELEASED AS OF TODAY!? Well, in that one sentence, I bet you can see how much I love the art. And how I'm a fan of Izawa Rei lol
Next, the story isn't too dramatic. It's a lighthearted read, and it's cute, and all the characters are so lovable. You can't hate Ryou, or Hakuou, or even that grumpy senpai of Hakuou's (cause he's a bishie lol). As far as I've read, there hasn't been that much drama except the backstory for Hakuou (I have yet to look for raws and read them).
The comedy is pretty funny too. And Hakuou, omg, that epitome of butler perfection.
My review really isn't that helpful, but that's because I know most of the readers for this manga LOVE this manga. I mean, I don't see why anybody should hate it. That, and I don't see anything wrong with this manga. It all works together and it makes you happy and hope you have your own Hakuou serving you lol
