Imo, this drama was far too lengthy for my liking. Like 24 episodes that are each over 1 hour is a bit overwhelming.

Story: The main two are extremely good at acting, Chaekyung and Shin take a while to envelope an actual relationship but midway you can how their love blossoms. I think the sweet times they have together are especially adorable! The story is interesting because it's about a royal family in South Korea.

Acting: Though there are some characters who I wasn't a fan of, I enjoyed the rest of the cast and everyone really made their acting realistic.

Music: Of course we're all familiar with 'Perhaps Love', if not, it's the best ost to ever exist, and one I will always tune in to listen to it. The other songs were also nice.

Rewatch Value: eh, probably not. This drama is too long. Even though I enjoyed it, I would not watch it again. I would probably just watch a scene or two on YouTube.

Overall, I'd give it a solid 8. But I'd definitely give it a try. It's known as one of the best nostalgic drama's in all K-dramas.
Extra: If you enjoyed Yoon Eunhye in this drama, then I recommend 'Coffee Prince', it's my all time favourite drama and the kiss scenes are to die for!! Eunhye has a really good role in the drama and Gongyoo is in it too :)
