A real hidden gem! I wish the updates were more frequent, but I've found this a fantastic read so far. The characters are very fun to see interact with each other, and the art and story have been quite compelling. From my perspective, this is also a very unique setting, taking place in China, in an Imperial Harem.
Even though the story is likely tailored to a female audience, I found this thoroughly enjoyable so far, being an adult male in my late twenties.
I suppose the closest thematic manga/anime I can think of would be Fushigi Yugi. Something that has occurred to me that's odd is that even though the names of the characters are authentically Chinese, the title of the manga is in Japanese. Just a curious note.
How long do these reviews need to be? I'm generally a person of few words.
