Female Imperial Son-in-Law and Male Princess
A modern female CEO, Lin Zhiyi, unexpectedly transmigrates into the body of Lin-fu's young marquis, who is disguised as a man. Even more surprisingly, she is chosen by the emperor to be the imperial son-in-law.
With only three months until her wedding to the princess, Lin Zhiyi thinks to herself, "If I have to marry, I'll marry!" As she is from modern times, she has a broad mind. At worst, it will be a yuri romance! A sweet and soft lady is not bad; getting close to her is fine.
Life, money, and power are the most important things. But then... Lin Zhiyi reopens her eyes and finds herself inside the princess's body, and the princess... has a penis!
Hmm? Body swap?! So the princess was a man in disguise all along?! Excellent, they've both got dirt on each other, a perfect tie. No one can control the other!
Jing Yue had been pretending to be obedient, hiding his sharpness, and acting as a gentle and compliant princess. Under his imperial concubine mother's arrangements, he had disguised himself as a woman for seventeen years, narrowly escaping many open and hidden attacks in the palace.
He originally thought that once he married the imperial son-in-law and left the palace, he could rest easy. Who knew that he would consecutively 'curse' two imperial sons-in-law to death, and his wish to leave the palace would be repeatedly thwarted.
He wondered if this third imperial son-in-law could survive until their wedding? The new imperial son-in-law was pleasing to his eye, was a good speaker, and had endless little tricks to charm people, which piqued Jing Yue's interest.
Perhaps he could draw this person into his camp and help him keep his secret? Unexpectedly, one day he swapped bodies with the imperial son-in-law!
Hmm? It's a female imperial son-in-law?! This truly is a once-in-a-century compatible person! It turns out that this time, fate not only brought him the right person but also placed the destiny of Da Yan on his shoulders.
She is a lucky star, a wise person, and his unique beloved. This is a love fostered by displaced identities; they are each other's sole salvation. It leans a bit towards an ensemble cast.
