Both FLs are the daughter of a man wrongfully accused and executed, and both assume a false identity and become swept up into some pretense regarding gender (marriage to a girl pretending to be a boy vs. attending school disguised as a boy).
This is similar in terms of the FL dressing up as a man to discover the truth about the massacre of her family. The FL is also smart like Wen Xi. The cast are all goodlooking as well
Why a school life show when it's not similar to the plot? Because it has the same leads! Waiting for The Eternal Fragrance, you can check out the leads chemistry in their earlier drama!
