first of all, i'm a fan of Lee Soo-hyuk. attracted to both his visuals & amazing voice.
I watched this drama mainly due to him, loves his role here. Quirky, smartar** with amazing comeback, and of course the ever confidence in his pursue of the second female lead.

there are shortclips in youtube as a summary for the second leads romance storyline, which I occasionally rewatched.
Aint no man exist in real life. His dedication & devotion to the woman he likes.

drama OST is also a big yes. Ailee's powerful voice brings up the feel everytime i listen.
