I've seen about three dramas with Lan Blue in them. He's not a very strong actor, but there's something that I like about him so I watch his work. He's improved a bit over the years. I really liked him here, and perhaps it has to do with his lead actress, Nagasawa Masami. They worked well together and she's a great actress. I liked the chemistry between the two, but I wish the writing had done just a little more with them. The story itself was simple. A gang of gangsters trying to go straight, mainly because that;s what the boss wants. There were ups and downs and I appreciated that. It made the story more enjoyable. There was just something about the struggle and them making a family of their own together that really pulled me in. I really liked the music here, especially the ending theme. The song is beautiful and the lyrics are really touching. I thought it described the relationships between the two leads perfectly. I found their romance really appealing because they were both trying to be really selfless. They wanted the other safe and happy, even if that meant they couldn't be together. The supporting characters were also great (super funny) and the ending was perfect. All in all, I say give this a try. I haven't read the manga and when I first heard about this I didn't see the appeal. I decided recently to watch the first ep since I hadn't watched a twdrama in a while and ended up watching all 15 eps in 3 days.
