[Single female protagonist + sister control + brother control + rebirth + no system + sweet text]
In his last life, Song Yu was haunted by the resentment of his younger sister who died young, and was unlucky for the rest of his life. In this life, his sister did not come into the world, but there was a little girl pestering him.
"Shen Qingxia, how much you like me."
"I love you so much that I want to be with you forever."
"Then we have known each other for several years."
"Thirty-eight years."
"Huh? We are only eighteen years old?"
"I said it, brother. It's life after life."
