Oh No! The Lovelorn Husband I Picked Up Is Actually the Crown Prince

[Farming + palace intrigue + doting on his wife + face-slapping + one-on-one romance] Zhou Yun'er transmigrates into the body of Zhou Er Ya, a village girl in ancient times. While gathering wild vegetables in the mountains, she stumbles upon a mysterious injured man. She takes him in, originally just hoping to gain an extra pair of hands around the house. Who could have guessed she would end up entangled with him herself!

That would be one thing, but can someone tell her why a group of strangers suddenly showed up at her house, calling her husband His Highness the Crown Prince?

Good heavens, has she suddenly become the Crown Princess?
