If you're looking for a feel good romcom then A Business Proposal is perfect for you.

It's a simple story of mistaken identity that leads to love. The writers know the situation is a cliche rich guy poor girl story and they enjoy making fun of it by depicting the various characters watching a drama with similar situations being portrayed as to what's taking place with the leads. There are many funny moments which makes the drama enjoyable to watch.

And for those who dislike the main leads, the second leads should win the show some brownie points. Both make a good looking pair and it is interesting watching them and how they overcome misunderstandings and their hesitancy. The grandfather is another loveable character and he plays a strict but loving father figure for the Male lead who is way too busy working his life away. I also loved the sister rivalry to sisterhood moment between Jin Young Seo, the second female lead, and her cousin, Jo Yoo Jung.

My reason for not rating this drama higher is only because of a few flaws/depictions I disliked. Shin Hari (female lead) works with her team manager, Yeo Eui Ju, and a development team member, Kye Bin, who eventually start dating. The show depicts them as eccentric older characters to make fun of. Their love and bickering is shown as funny and somewhat distasteful. Also, the toilet scene jokes were a bit boring and overdone. And of course the show hits nearly every major romance cliche so there is no real surprise element to the show (until ep 10).

Despite these negatives, I enjoyed it a lot and most people would probably enjoy it too.

Edit: I have actually given ABP a 0.5 higher rating than my original review because I actually believe this is one of the most enjoyable romcoms I've come across and I have seen less enjoyable shows with the same rating ao it's only fair that it's entertainment value be considered.
