This is a very solid BL, especially considering the fact that it's from GMMTV. I enjoyed seeing Pond and Phuwin act in this drama and seeing how their acting skills have improved since Fish Upon the Sky. This drama is not light-hearted and features some unpleasant themes like the death of family members, or being outed as a gay person. But the producers made the cinematography align well with the themes, which is something they should be recognized for.
Something that I appreciate this drama for is how they did product placement. I know with GMMTV dramas the product placement scenes tend to be really obvious and take away the emotional effect of the scene. Although this drama did have a couple of product placement scenes, it didn't over-highlight the product and therefore I was still able to appreciate the scene for what it was.
To sum up, what I think of the drama as a whole, it's a toned-down version of KinnPorsche. It has the mafia, the gays, and the romance between the boss and his bodyguard.
