I'm probably in the minority here but I just couldn't STAND Siwon's character. Sure he was funny at first, but later he just got on my nerves, especially when all his jokes and craziness were at Hye Jin's expense 90% of the time, I just didn't find it charming at all. And there comes a time when the second male lead needs to realize he's the second male lead, which didn't happen early enough IMO they just kept dragging it out. I did enjoy the drama otherwise (despite the male lead being the tear-inducing arrogant asshole he was in the beginning). I really liked some of the other characters (the second couple was super cute and the main couple too when they got together). I loved Hye Jin's and Ha Ri's friendship, Park Seo Joon is great eyecandy of course, there were a lot of comical and sweet moments and the OST was nice too.
