I didn't think I would love this drama so much when I first started watching this. Honestly, at first I didn't like the main characters so much, because I didn't really think they looked good together and probably because the last time I saw Seo In Guk was Master's Sun (all sweet) and Jang Na Ra in Mr. Back (the drama which I think was boring), but after watching few episodes I got really addicted to both the drama plot and ost. Almost all the characters are amazing in both acting and character, especially the mains. The chemistry between them is getting stronger and cute. I just love Lee Hyun's eye when he looks at Cha Jin An sometimes; they're so sweet >_< Cha Ji An is not really a character who just depends on the main guy and gets more cuter when it comes to romance between Lee Hyun. It's better to watch some episodes before you start to not like this drama.
