Black Moonlight is here, please take your place.

An ordinary girl, Chi Anning, unexpectedly transmigrates into a male-oriented fantasy novel, becoming a vicious supporting female character tasked with bullying the male lead, Shen Shu, according to a system's requirements; failure results in her being eliminated. However, she is kind-hearted and soft-hearted; her "bullying" is actually a form of coquettish command and silent protection, leading Shen Shu to mistakenly believe he is in love and fall deeply in love. Ten years later, the system forcibly jumps to a new era. Shen Shu has become a business tycoon, aware of the system's existence, but refuses to expose Chi Anning's "fake heiress" identity according to the original plot. Instead, he obsessively pursues her, even attempting to detach from the system and forcibly bind to it. Chi Anning's body deteriorates due to failing to complete the "death offline" mission, and the real heiress, the second female lead, teams up with her parents to kidnap her. Ultimately, the system exhausts its energy, tearing open the spacetime barrier and sending Shen Shu to the real world, where the two are reunited.
