I'm going to be honest. I watched this show because I was curious why it's so hyped. Now, I understand it. It's all about the chemistry between the two lead actor! Overall the show was great, the acting, the whole production was top-notch, also I loved the OST too. I only gave 8/10 because the actors did a great job and the overall feeling of the show was good. It is a typical cliché KDrama for sure, BUT I was honestly surprised that there wasn't a HUGE problem with the whole "poor" girl dating with the billionaire guy. Usually they're stretching this type of story for 10+ episodes, but huge props to the writers not doing that on this show. It was refreshing that most of the characters felt real and they weren't overdramatic. I watched 'King the Land' right before 'A Business Proposal' so most of the storyline felt the same honestly, but this is just a minor issue. My biggest problem was the whole sister vs brother story. It was totally unnecessary, at least the way they did it. Also, they should've done more with the mother story too, but that's all, basically. One thing's for sure, Yoon Ah and Jun Ho set the show on fire.? I know they finished the story well, but I would love to see a 2nd season. Lastly, my favorite part of the show is the friendship between the girls and Da Eul's daughter, she was a little savage.? The main Supporting Cast were fantastic.

I know there are people who afraid of the hype, but I'm probably one of the biggest critic when it comes to overhyped shows or movies. So, trust me, this is a fun ride for sure. Not perfect, but to be honest, there's not a lot of perfect show, especially in KDrama world. Not to mention, that seeing Yoon Ah's smile worth every minute you will spend on this show. No wonder, she's the "IT GIRL" of this generation.
