Just one word: funny. I laughed on almost every episode for this drama. This is so entertaining to watch, especially when you're just stranded at home in this pandemic and can't go out. Every episode is only about 20 minutes (minus the opening and closing theme song), so it's easy to binge watch the drama. I initially watch this drama because of Xiao Zhan, but ended up liking many of the characters. My first Zhao Lu Si drama and she is so funny in most scenes that she's in. The story is about time travel, similar to Scarlett Heart and The Eternal Love, but this one is more entertaining and easier to digest. I like the ending theme as well, so I never skip the songs.
