I kept starting and stopping this drama, its a bit heavier than I'm used to. But after the second episode I was addicted. The story is quite dark, many people have said it was easy to guess what was going on but I didn't guess at all. Lots of violence and action scenes, which were very well done. No cartoon punching sound effects that ruin so many drama fights. The acting was A++. Although I am a huge fan of both the leads, so I am slightly biased. I really enjoyed seeing Shun and Toma in a drama together again, the chemistry between them was brilliant. You really believe they care about each other. I wouldn't say its very re-watchable. Its quite heavy and tragic. Its not what I'd call an easy watch.
