This was my first Kdrama, and it's the reason for my current addiction to them! I loved watching Lee Min Ho & Son Ye Jin's love/hate relationship develop. There are so many sweet scenes between the two of them, and scenes with an overload of sexual tension. They had such great chemistry that the old opposites attract formula never felt boring. Some of the scenarios in the beginning are a little far fetched, but it's kdrama so what do you expect. I laughed out loud & cried as the story progressed. I rewatched certain moments over & over. There is a drastic shift, which is pretty common in KDrama, where the romantic comedy suddenly turns into a tear jerking drama. I definitely had more fun watching the first 11 episodes, but I think there was a pretty seamless transition to the sadder later episodes. I admit, after a rewatch, that some of the moments that broke my heart the first time seemed a little overdone this time, but the acting was never bad. I think overall that learning more about Park Kae In's sad past made the story feel more complete. Some of the final romantic scenes are also a little cheesy, and Jeon Jin Ho becomes super frustrating, but I honestly still loved watching every moment. I think the whole cast was great! I loved Jo Eun Ji as the bff, and her hilarious relationship with Jung Sung Hwa. I loved how Ryu Seung Ryong's character developed as well. He could have come off as creepy, but instead he was super sweet (err... no pun intended). Kim Ji Suk & Wang Ji Hye were incredibly annoying, but they were supposed to be. I could have skipped through their early storyline though. As for the leads, I really started to relate to quirky Park Kae In, and Son Ye Jin did an excellent job of not overplaying her gullibility and sweetness. As for Lee Min Ho, I haven't been disappointed by a drama with him in it yet. Lee Min Ho fans should definitely see this one, in spite of his high water pants. I also have to mention the soundtrack, which remains one of my favorites. I still don't get tired of hearing the songs over & over again during episodes "Babo cheoreom..." ; ) I may be biased since this was only the 2nd drama I ever watched, but this is hands down one of my favorites. I decided to rewatch/re-review Personal Preference almost 30 dramas later, to see how it still holds up. It's still one of my top favorites, and still has one of my favorite k-drama first kiss scenes. I definitely will rewatch this more than once, and I admit that I listen to the soundtrack sometimes because I miss it, lol.
