Traveling through time one day, she became the village chief family's little girl whose intelligence stayed at eight years old and who couldn't even take care of herself. Ahead were two protective yet honest biological older brothers, and behind was a nagging sister-in-law who loved to gossip and secretly trip her up, making her days miserable and spineless. She originally wanted to slowly warm her family's hearts and cure her foolishness, but who would have expected the village chief father to suddenly flip out a letter sealed for fifteen years, which turned out to be an arranged marriage casually set for his daughter back then! Now, the in-laws' family really came looking for her, and the male's household stated in a letter that she should enter the city after the new year, and have them marry after a period of contact.
