Time Travel: Substitute Marriage for the Crown Princess

She is obviously the legitimate daughter of the Hou family, but her life is worse than that of a concubine. What kind of life was she spending this time traveling through time? Although she didn't have enough to eat or warm clothes, no one cared about her, so her life was quite comfortable. But she never expected that one day her aunt would suddenly come to visit and she would be given a big yard, clothes and jewelry made for her. As the saying goes, when things go wrong, there must be a monster. When a weasel pays New Year greetings to a rooster, he must have bad intentions. She asked the little girl next to her to find out, and it turned out that her aunt wanted to marry her to a famous dandy in the capital. Not to mention that the prince is a dandy, but I heard that he is also a slave to his wife. The aunt's mother did not want to marry the daughter she had raised by her side, so she asked her to marry her instead. Because she has better arrangements for that daughter. As for her, instead of staying in the Hou Mansion all day, which is totally meaningless, she might as well get married, change places to play, and just marry as a substitute. It doesn't matter to her, anyway, it doesn't matter who you marry in ancient times. But she later discovered that the prince's so-called dandyism and wife-suppression were only spread by his mother-in-law. Since they share the same problem, let's work together to fight against the evildoers...
