This show presented that Marijuana was cure for the elderly, and yet this show just blindly follow its antiquated law and culture.  While this show and a lot of kdrama is happy to show how the Korean  culture loves alcohol.  Well , alcohol is no cure and kills especially the elderly. and weak. Cigarettes and alcohol are definitely addictive and Marijuana isn't.

The most ironic part is the "Law" in the title of this series.  They could have presented that the law sometimes isn't perfect nor even good for its citizen.
