While the reunion scenes are sweet, the talk amongst 3 of the 4 princesses is a little strange to say the least. It would be curious to at least confirm if the 4th princess was also of the same mindset, as well as if King Yawen would continue to visit them as bride candidates even thought it's now clear it's Ruiying he's interested in, and she returns the interest even if she's only just starting to realize it or understand anything. The ending doesn't feel like a true ending or conclusion though, so while it has a lot of potential, it feels like the overall story missed out on a lot of what it could have been.
