The story line is good, the development through each episodes is good..makes you wanna know what's gonna happen next. The only thing is...although I think Lee Min Ho did a very good job in his acting Son Ye Jin is not quite there. Her acting was purely acting, I don't think the clumsy kinda stupid girl character suits her very well. She just look trying hard :(( It could be better if they choose another actress who's more suited for the character..but overall this is a good drama to watch.
