Qin Huaiyu transmigrates to the Tang Dynasty, where Qin Shubao relentlessly tries to find him a wife, until Li Shimin seeks a husband for Princess Jinyang, little Sizi.
Qin Huaiyu has studied history and knows that becoming a royal son-in-law means a fate worse than death. A man of iron will, he boldly declares that he would rather die than marry a princess.
But Li Shimin, concealing his identity, takes little Sizi out of the city in disguise. When Qin Huaiyu sees little Sizi's veil fall, he is struck by her beauty.
Grinning, he looks at Li Shimin and calls him "Father-in-law!"
Li Shimin looks at him with a beaming smile.
Qin Huaiyu still has no idea that the man before him is Li Shimin, or that little Sizi is the very princess he swore he would rather die than marry.
The next day...
A memorial lands on Li Shimin's desk: Qin Huaiyu beat up Changsun Chong. The boy is a wastrel and unsuitable to be the emperor's son-in-law.
