After Becoming the Real Heiress in a Period Novel, I Decided to Lie Flat

In her previous life, Si Si died suddenly from overwork. When she wakes up, she discovers that she has transmigrated into a historical novel about a real and fake heiress. The good news is that she's the real heiress. The bad news is that this is a story where the fake heiress is adored by everyone. The real heiress is the daughter of a city family, but she was switched at birth and grew up in the countryside, suffering plenty of hardship. Though her identity is eventually revealed, she ends up as a foil for the fake heiress. The fake heiress has loving parents, protective brothers, and a childhood sweetheart from the family compound. Naturally, the real heiress can't accept seeing the fake heiress surrounded by admirers. Unfortunately, anyone who opposes the heroine meets a bad end. After repeatedly causing trouble and offending everyone, the real heiress becomes destitute and lonely, and lives out her short life in misery. Si Si sighs. From the real heiress's point of view, it is hard to say that everything was entirely her fault. But now that Si Si has transmigrated into the story, she decides to give up on opposing the heroine. As long as she keeps her head down and doesn't cause trouble, surely she won't have a bad life. All she wants is to get into a good university, land a secure job, ride the wave of the times, save up for a few houses, and then lie flat as a landlady collecting rent for the rest of her life. Wouldn't that be wonderful? Right, she should also keep her distance from the heroine's childhood friends from the family compound. But surely there's no harm in lending a hand to this poor little thing right in front of her? P.S. The male lead doesn't appear much.
