Unbelievable! What Kind of Little Villain Gets Hounded by the Hero and Turns Into a Simp?

[Quick Transmigration] [Two Male Leads] [From Universally Hated to Universally Loved] [A Disciplined Male Lead, a Dominant Main God]

The young man is a fox spirit whose true form is an adorable fluffy white ball. After an accident, he is forced to bind himself to a System.

The System promises that if he plays cannon fodder and villains in various small worlds and advances the leads' romantic relationships, he'll gain the formidable power to become a great demon in his own right.

The little fox, dismissed as useless by his kin since childhood, is tempted. He chooses to throw himself into the world of quick transmigration without hesitation.

In the first world, he's the fussy boyfriend of the protagonist. The protagonist works three jobs to support him every day, while he squanders the protagonist's money on frivolous luxuries.

That's not all. He also verbally abuses the protagonist every day and psychologically manipulates him.

In the end, the protagonist finally sees the light, dumps his fussy boyfriend, and sets out on the path to becoming a business mogul. Along the way, he finds true love.

After transmigrating, the little fox works hard to complete his missions and maintain his character, but for some reason... the plot suddenly goes completely off the rails. The protagonist, once a harmless little white rabbit, turns into a ravenous wolf, and his blackening level shoots up at an alarming rate.

The utterly bewildered little fox trembles in fear, but still can't escape being bound to the protagonist's side.

In the end, even the other protagonist starts acting strangely, abandoning his original wife and choosing his love rival instead.

His roles in the other worlds include:

A treacherous minister who commits every manner of evil, a demonic cult leader guilty of countless atrocities, a white-haired Gu master from the Miao borderlands, the rich second-generation brother of a scumbag male lead, a scheming little green tea in the apocalypse, and an arrogant top-tier star singer.
