This is one of those forgetable kdrama that you watch in order to fall asleep. Its plot is outrageously uninteresting and it would somehow seem like a promotional film for Cuba.
The lead actor needs to go to acting school. The supporting actor is far more better 110% .
The female actress seems to know how to act but lacks realism in delivering her role.
Anyway, there are far more better ways to spend your time, unless you want to be lull to sleep.... very slow phase - when you fall asleep you wont miss much :)
