What hooked me in right away was Gong Yoo's masculinity on the very first episode. I mean who could resist that charming smile and beautiful eyes? On top of that he's a talented actor and sings well too. I wasn't convinced by the main female lead at first but she gradually delivered admirably as the story progressed. The chemistry between them bloomed beautifully towards the end. There's a great cast surrounding them too and they carried the weight of the story well. Definitely an interesting love story to comfort you on your days off.
