I've just finished "Be My Angel".
It's very cute, but its quite silly and the plot is very thin. Nothing really happens, or at least nothing of any real consequence. It sort of gets a little bit interesting in episode 7 for a while, but that's about it. The actors did a reasonable job, but no one was given any opportunity to showcase their acting skills. I'd like to see both lead actresses in a more serious drama to see what they can do. The production and cinematography were both very good, so there's that at least.
If you're a fan of super-fluffy, silly romcoms and don't care if the plot is lacking, then you might enjoy this drama. If not, then perhaps give this one a miss.
I've scored it 7/10, which for me means it is below average, but not terrible.
