I love Japanese light dramas and this one checks that box but after finishing it it was a huge let down.
It has a nice story, good cast, a mystery and great villain and I'm not really picky with Jdramas, if it's enjoyable enough them I'm in.
But the final product is far away from this great combination I mentioned making me slightly unsatisfied.

Acting was nice, I like Hikaru but Shiraishi Mai here wasn't at her best, also I loved Junpei and Joichiro roles. The whole cast was nice Nevertheless none of them were very good, just average at max.

The story is a total mess, and I'm only talking about the parts they promised in the plot, the comedy part was non existent, the hate-to-love troupe was totally a miss and there is nothing memorable about the drama.
The whole bodyguard part lasted for the first 2 episodes maybe then it's all about the crime, they took so much time showing how endangered Rika is in the first episode, only to push her to be a side story, the rest of the drama was very very predictable, you don't even have to think about anything the mystery was solved right from the beginning.

The series as a whole was acceptable, slightly choppy and very random but watchable.
