It's your typical manga turned Jdrama adaptation. Hire actors where specs trump acting capability. What starts off strong as a murder revenge plot quickly turns sour due to terrible pacing. It was actually good in the first half, especially around episode 4 or 5 or so, but then becomes mediocre due to a shoehorned love triangle and a pregnancy. It's supposed to be romance but there was no chemistry at all between the leads. The female lead was marginally better than her male lead who wears a poker face the whole time. I felt nothing when they broke up. On the one hand, it was supposed to be a murder mystery but on the hand, it was a bad soap opera. The ending was at least ok. I ended up caring more for Tsubaki's mom than his whole relationship with Nao.

The gist of drama is Hanaoka Nao goes undercover under a false alias and a fake marriage contract with her childhood crush Takatsuki Tsubaki at the Kogetsuan, the place where her mother last worked. Her mom was wrongly accused of a crime she didn't commit. Nao wants to undercover what really happened to the late heir to Kogetsuan and why and how he was killed and ultimately salvage her mother's name. From there, the pacing just falls apart. On paper, the plot sounds great.
