I want something like "Which Concubine Doesn't Know How to Stir Up Trouble?" Every time I read the blurb, I get hooked. Before picking it up this time, I didn't realize I'd already read a hundred chapters before and then stopped for some reason. This time, though, I finished it, and I bawled my eyes out at the ending.
