A Female Supporting Role in a Book, an Educated Youth Who Went to the Countryside Counterattacked and Became the Heroine

(A scumbag + a sweet pet + a delicate and contrived little fairy, etc.) Reborn on the train going to the countryside, Long Beibei realized that she was now in a novel world, and that she was just a childhood sweetheart that the hero had known since childhood, and a female partner who died young! She has been delicate and frail since birth, and there is not much writing in the book because she died young! Long Beibei didn't believe in fate, so she decided to turn things around and win over the male protagonist, and get married to him. Not long after she got married, she and the male protagonist went with the army. Unexpectedly, fate played a trick on people, and the male protagonist in his previous life became a short-lived person. She fell asleep alone and woke up forgetting what happened before. There is always a big dog next to me, the kind that is always there when called. Sometimes it can't be beaten away or scolded but won't run away. It often likes to laugh silly and like to tease people. It was such an annoying guy that made Long Beibei miss him. So prepare to start a new life... "The entire text is fictional.
