I Rely on the Villain for Survival [Quick Transmigration]

Content warning: The female lead has rock-bottom intelligence and emotional intelligence. The story focuses mainly on family bonds, with little romance. Look here, look here, look here. Important things must be said three times: the female lead really is very stupid. If you decide to keep reading after seeing this warning and find anything upsetting, please do not attack the author. As an upstanding young person of the new era, Su Yuanyuan was selected by the World Peace Organization for the "Clinging to Each Other for Survival" (Deadweight) Program. As Deadweight No. 1, Su Yuanyuan's mission is to transmigrate into various worlds and become the villain's last remaining family member. Using her rock-bottom intelligence and emotional intelligence, she is to move the villain (and drag him down). She helps the villain gradually let go of his dark mindset and devote himself to looking after this useless deadweight... until he reaches the pinnacle of life, marries, has children, and lives happily ever after. So Su Yuanyuan ends up with countless identities: the villain's only surviving younger sister, junior sister, sworn younger sister...
