[Soul transmigration + cross-dressing as a man + royalty + sworn enemies]
Cheng Muan is a science and engineering student about to take her postgraduate entrance exams. After studying through the night without a break, she suffers an unexpected cardiac arrest and transmigrates into the body of Cheng Muan of the Qi Kingdom, who shares her name. But in this dynasty, Cheng Muan is a woman pretending to be a prince. Worse still, just before she arrived, this Cheng Muan had provoked the cold and calculating Prince Jing'an, Cheng Xiaoyu. Great. The original owner provoked him, then left her to deal with the fallout after taking over her body... The original owner didn't suffer at all. She left all the hardship to me (X﹏X)
