This is a super cute drama that randomly piqued my interest. I never saw or heard of the original, so I started watching knowing nothing about the story other than the genre. For those of you in the same boat, know that this is 100% romance, so if you are looking for a complicated or emotional storyline you should look elsewhere. The love story is also very cliché... a sweet average girl and an abrasive arrogant chaebol get involved in a relationship contract... but because the show is literally about watching their developing relationship, without a lot of filler, the story still somehow feels fresh. Ha Suk Jin and Jeon So Min are a great match. They not only play their roles well, but they have very realistic chemistry with each other. Watching them felt like eavesdropping on an actual couple, even with all the tropes. I especially loved the way he looked at her, and it's worth noting that their kissing moments are much hotter and realer than the kdrama norm. I've never seen either before, but they nailed it. The only reason for lowering my cast score was that although I loved the leads, the best friend, and Jae In's lawyer, many of the supporting cast members seemed pretty useless. A lot of them didn't have enough screen time to make me care about them, or just had a ridiculous role like Seo Eun Chae as Han Joo Hee. I'm not sure if she or the role were the problem, maybe both, but although I can see how she added to their story, she was my least favorite part. I also gave the story a lower score, because of the lack of originality, poorly fleshed out backstories, and a few "dramatic" moments that made no sense to me, but what they did well was trim a lot of fat from the episodes. I confess that I actually binge watched this whole drama while sick, and I was able to finish it in a day and a half! I was on episode 4 before I realized that the episodes were shorter than usual, and that's also when I finally gave up on waiting for a big dramatic story to happen. The episodes seemed to fly by as I watched Jae In and Dada become closer, and that was all the entertainment I needed. Would I watch this again? Maybe. I liked the main characters enough for a possible rewatch, but I can't say the same about the rest of the plot. Oh, and the OST. It's a great match for this drama, including a cute spinoff of the jackson 5's "I want you back", but I was pretty indifferent to Ji Soo's songs, and his storyline. Overall, this is a good romcom, and definitely worth watching for fans of the genre. I think my score is lower than most because I tend to like more intriguing plots, but this simple story has a lot of charm. I also think making it shorter was very smart (I can't believe the original was so long), so there was no time to get bored with the story, and it took no time to get hooked. It's the perfect drama for weekend binge watching, while still leaving you with some time left for real life (If you're not sick like I was)! I'm glad I took a chance on this one.
