This manga is quite good, especially for a Nakamura Shungiku one. I usually don't rate her mangas very highly because yes, they are indeed dreamy, but that's because she always uses the technique to make them as cliché as it gets and never a bit original. Very same reason Junjou Romantica is the top anime at the moment, it's all a big compilation of things that people like in yaoi.
I'm only talking about the two first stories here, but they were overrated. Generally, the idea of the "dolls" it's pretty new in the way she puts it, growing with affection and everything. I especially liked how she didn't focus it the story in the relationships themselves as male x male ones, but in the way the HCs and the masters were connected, regardlessly.
The first story was very cute and touching. I really loved how she developed it and how it ended. BUT it lacks some explanations. For instance: what is Hazuki's past? Why did his previous owners throw him away? How did Kuroda fix him after all? What the heck is the moon droplet? Oh, and I'm really fond of Hazuki being so tall, since it comes from receiving Kotarou's love~!
The second one is pretty good. Seya's amazing, I can't even begin to describe him. Even being a short story, he had such a captivating personality! There's much more deepness to him than only the kindness he shows towards Yuzu. The age gap in the beginning did bother me a little, but in the end, where they used the always immortal Nakamura-sensei's catching phrase, it was beautiful and emotional. It's really pure and lovely! Pretty predictable why he didn't grow, but even though I knew it since the beginning, I didn't care, and I think that means the plot is good enough to get my attention.
The first two left me with this doubt, though: did all of the couples actually become lovers or remained as they were before? I know it's shounen-ai, but it's sooo light =/
The third one is an exception to everything I've written, because it's indeed as amazing as everybody else said, if not more.
It's beautiful, touching, heart-wrenching. What makes it special is, not only the plot development and the story itself, but the way Tsukishima and Kuroda's relationship develops. But most importantly, the ending. You know, every time a characters dies, everybody gets so pissed off, but that's what makes it unique. It's so painfully sad that I almost regretted reading it, but because of that, it's a story that I will never forget.
I love it.
