Buissness Proposal is exactly what you would expect it to be from the title and the cover picture ; a cheesy, lighthearted, rom-com. You don't go into expecting anything groundbreaking and by the end you find those expectations met.
The first few episodes are definitely much better, and much funnier, than the final episodes. At the begining of the series it's hard to stop watching but by the end it gets tedious.
The conflicts feel unnecessary and the the lack of any wedding by the end makes the drama end on an anticlimax.
Overall, its not a bad drama and it's a fun, easy watch, but is it anything new, exciting or unique? Definitely not.
