i was annoyed with princess kyunghye at first because she didn't want the FL to see the ML in the beginning, but rewatching you realise that she's just trying to secure her brother's reign by marrying kim seungyu because kim jongseo supports her father (king munjong)
i watched the whole drama and especially now after having finished it about 2 weeks ago, I still wonder why I kept watching this...the female lead is still annoying thinking about this drama lol
