I found some recommendations for novels that start off as the protagonist's brother. Among them were Elite of Breaking Things: Becoming Sha Lele's Brother at the Beginning and Assassin Wu Liuqi: Becoming Qi's Brother at the Beginning. These novels were all about urban life, about the protagonist being reborn or transmigrating to a new world and becoming the brother of a certain character. These novels may provide a series of interesting and exciting plots, as well as descriptions of how the protagonist deals with new environments and interactions with other characters.
