Lu Changling is a delicate, sickly beauty of an alpha, gorgeous and wicked. He pretends to be an omega to string along his long-distance boyfriend, while streaming to hook a sugar daddy. Then he picks up a novel from the adult fiction site and discovers that its villainous cannon-fodder character has the same name as him.
The villainous cannon fodder loves playing the field and keeping a whole pond of fish, living off several different lovers, yet still greedily wanting more. Eventually, his long-distance boyfriend discovers his explicit livestreams, sees him for the vile and greedy person he is, and dumps him without mercy to find true love elsewhere. The cannon fodder's real identity is also exposed. His reputation in tatters, he is expelled and shunned by everyone, left with neither money nor status.
The next day, Lu Changling runs into one of the male leads at school: his archrival. At last, he realizes that the novel seems to be his fate.
System: Congratulations, you've awakened. Will you keep being a villainous cannon-fodder character, or turn over a new leaf and become a good person?
Lu Changling doesn't want to be good. Not only will he keep living off other people, he'll make sure they know who's in charge!
His archrival discovers his identity as a streamer. Lu Changling insults him, uses his lap as a chair, then laughs and asks if he's comfortable.
Humiliated, his archrival trembles and turns bright red. Then he goes on a wild tipping spree, becoming Lu Changling's top supporter, and demands that he wear a specific thigh garter.
He bosses his ex-boyfriend around, making him live in his house, do the laundry, and cook. He tries to force the guy to break up with him so he can find someone more obedient.
His ex-boyfriend coolly washes his underwear and tells him not to let anyone else do those things for him.
He treats his unrelated younger uncle as an ATM. When refused, he snidely says his uncle is too old and too weak to earn money, and that he'll find someone else to be his ATM.
His uncle pulls out a thick stack of bills, spanks him with it, and teaches him that the only person he should be gold-digging is his darling uncle.

Theme: If only everyone would give a little love.
