I only started this for IU and Jang Geun Suk (after having watched them in Scarlett Ryo and You’re beautiful). I only finished it because I have kind of a problem with dropping anything and for Lee Jang Woo and partly IU.
I like her very much, but I didn’t get the plot of the story, there are flaws everywhere, no chemistry between main leads and overall, nobody who is so bad treated as IU would continue loving the main lead (moreover with so many awful hairstyles as him), having someone as David Cho beside her...
So, the only positive thing is that sometimes the instrumental music was ok...Only watch it if you have tons of free time and nothing better to do.
