I accidentally came across this and decided to give it a try because of its plot and I was impressed. Although the first episode was okay, the story picked up from the second episode. For someone who has a crazy sweet tooth, I literally wanted to try all of the sweets they showed on the show. I had no idea that Japanese sweets could be so visually pleasing. Coming to the actors, I didn't see any of their previous works so I guess it's safe to say they've done a pretty good job. Although I must admit I hated Tsubaki's mother to the core, at some point in the last episode I actually felt a tad bit sorry for her considering how she became, the person she became. The actress who played the mother's role did a splendid job because she actually made me hate the character.
The plot is quite engrossing. I'm not sure if it's worthy to be called a spoiler but up until the end I was suspecting so many people but the actual culprit. And I liked the way they ended the show, it was a good ending, I'm kinda satisfied. It's a happy ending(for most part). And I really wanted it to be longer, in terms of the number of episodes. If you're thinking to watch it, I suggest you give the first two episodes a try and then decide. I'm pretty sure you won't be disappointed if you do watch it till the end. It's only 8 episodes, so not too many episodes to watch :)
