Lu Xi brings a walkthrough system and time-travels into an ancient romance novel world. Relying on a bottle of 'Obedience' potion, she captures the tyrant Fu Zhaoting, believing she has the emperor completely wrapped around her finger. Little does she know that the potion's validity period is only one day, and Fu Zhaoting woke up long ago, pretending to be clueless while knowingly playing along, willingly acting as her 'obedient puppy' for half a year. From feigned cooperation to quietly falling in love, the contradictory tyrant bestows all sorts of secret affections, and the two rush towards each other in a comical tug-of-war, ultimately achieving a happy and sweet imperial union.
