I started watching this drama because Hikari Mitsushima is my favorite japanese actress, and because I love thrillers. And it didn't disappoint at all. The story was beautiful, much better than I expected at the start. There are quite a few plot twists here and there, and that made the story very exciting and interesting. The cast was WONDERFUL. This is one of Hikari Mitsushima's best performances ever (only surpassed by her performance in Woman, another beautiful drama). Eita was fantastic too, he is quickly becoming one of my favourite japanese actors. Shinobu Otake, Shunsuke Kazama, Jun Fubuki and Saburo Okito were great too. The music was the worst aspect of this drama, but it was good anyway. It's certainly hard to watch, and the story is VERY dark at times, but I recommend it to everyone who is a fan of Eita or Hikari Mitsushima, and to those who are looking for a great story.
