Oh, wow, I loved it! It's not a masterpiece that would change your life but definitely an enjoyable work. I adored Yujin's personality, he was totally great for an uke. Those dialogues and word-battles he had with Willis... awesome. 😀 Willis was a great character, too, with his pervy ideas, and they make a fantastic match.
Well, there wasn't really any plot or what, it's more like a slice-of-life, but you won't get bored during the chapters and you will meet a lot of interesting side characters. (mostly bad guys) The art is typical Hashida-sensei, which can be either a plus or a negative point depending on the reader's taste. As for me, I like it.
As Zandra mentioned in the comment below, I'm also wondering about the 2nd volume. If Juné's not planning on publishing it, someone should really scanlate the continuation. The first book was fine, too, but I can't say the main charas got together. It would be so great to see how Yujin finally gives in to Prince Charming! 🙂
And also I'd be lying if I said I wouldn't want to "witness" their first night together. :P Though I have to admit those fantastic kisses were satisfying enough, too. ^^)
If you would like to see the interactions between a refreshingly disinterested uke and a naughty/cute/willful prince, I do recommend this manga. 😉
