Yuan Jing, a female graduate student at the Academy of Agricultural Sciences, wakes up to find herself transformed into a fake prince disguised as a woman who sneaked into the palace.

She only wants to farm and do scientific research, but her dad wildly shoves the imperial throne at her: "My rivers and mountains are handed over to you!"
