This drama doesn't have many episodes, so for the few episodes it has, it contains a good and interesting story. It is not really chlichee, but it also isn't something new or unique. I guess it's somewhere in between. But let me tell you, that it is easily interesting and beautiful enough to keep you captivated through all 9 episodes^^
The acting can be a little bit over the top, but that's not something new in asian dramas. Otherwise in my opinion it is really good acting from the main and second leads.
The music is, let me quote Jisoo "not bad but not good"
It is a drama that you can rewatch easily at least one more time.

And now for all big romance fans like me, a little checklist, so you know what to expect^^
No break up (This is a good one!)
No love triangle (I know hard to believe right?)
A little bit angst, but not that much :)
Slow burn romance (Really slow burn, but the way until they get together is it worth^^)
No evil in-laws
