This has become one of my top cdramas ever, and not just in 2023. Absolutely everything about this was a joy to watch, but I especially loved the relationships between the characters. It's hard to find a drama nowadays that doesn't focus on romance, and this drama is an example of one that's perfectly done even without one. The production was top notch, and everything just looked high budget and realistic (martial arts, settings, costumes etc) which made it so easy to immerse yourself into their story.

100% would recommend - watch for the friendship and the mysteries!
