Ugh, I Became a Fake Heiress and Still Have to Earn Money to Spoil the Villain

[Anti-doting heroine + secret identity + strong female lead] Shen Xingwan transmigrates into the role of a cannon-fodder fake heiress whose life has been planned from birth to burial. Under the System’s relentless supervision, she is forced down the path of taking out the beloved heroine. All she wants is to lie flat and live like a lazy fish, but she accidentally gets entangled with a frail heir who can’t even look after himself. “Wanwan, the physician says I’m deficient in qi and blood. I need some top-quality ginseng.” “Wanwan, I can only wear the finest silk, or I’ll have an allergic reaction.” “Wanwan, cough, everyone outside says I’m living off you. You don’t mind, do you…” Watching her savings shrink by the second, Shen Xingwan wonders what she did to deserve this. Not only does she have to fight the heroine and punish scoundrels, she also has to earn money to pamper the frail villain.
