The story were super intriguing and the cast totally hats it off. The depth of the character was quite good as well. Totally not a usual romance drama but it's really worth to watch.

The beautiful cinematography, kimono and wagashi (Japanese Sweets) will also get you hooked.

I keep guessing in my head in each episode who's the killer and near the end I also try to guess who's tsubaki's real dad.
This drama also portrait human character really well, like tsubaki's mother who's antagonist but in the end it was revealed she's not always bad and really care about tsubaki.
