Su Baek-hyang, the King's Daughter (2013)

It's the usually daily format so temper your expectations accordingly before proceeding any further. Both Seo Hyun Jin and her character contributed a lot to the drama to keep it decent enough. Her interactions were the most memorable. On the other hand, the writer robbed off Seo Woo from making her a decent character, writing wise. Meanwhile, Jo Hyun Jae was as static as always throughout his entire career, the man would rather die than changing his expression. There's no justification for the long runtime other than they were contractually obligated to follow the template dedicated to this time slot. At least give the high moments more time to sink in. Especially the ending, there was no need to make it this short, they had the time to take a more relaxed approach.
