Started watching this drama for YamaKen, but unexpectedly found some actors I already knew and loved: Matsuzaka Tori, Matsuhige (the one who played father), and Honoka Miki (the Itazura girl)...
The plot was convincing and kept me on the edge of the seat. The plot twist it was something I didn't even think of. It was maybe I finished the drama in two sitting.
Another thing that you may also love is that duration of episode is just 20-22 mins.
I'd highly recommend this drama if you are a J-Drama fan.
By the way, I liked the acting and I'm quite comfortable with it, but some people may find it bit unrealistic.
One thing that I love about Japanese content is that, unlike Korean Content, they deal with different subjects, and aspects of life.
