After I Failed to Reform the Female Lead of a Tragic Novel

Synopsis: 

Gong Dongling transmigrated into a substitute-themed angst novel and became the frail “white moonlight” who spent every day making trouble for the female lead—a white lotus supporting female character.

System: In the original novel, the female lead blackened because the plot was far too cruel. Your mission is to redeem the female lead and stop her from falling into demonic corruption.

That very night, Gong Dongling found Xie Yu—the pitiful little  female lead locked in the confinement room and trembling all over. She reached out her hand and said, “A-Yu, I’m your senior sister. From now on, Senior Sister will protect you properly. No one will ever bully you again.”

To let the female lead  feel the warmth of the world:

When the female lead  was covered in wounds and unable to cultivate, Gong Dongling delivered medicine and refined pills for her.

When those scumbag male leads mocked and humiliated the female lead, Gong Dongling stepped forward and angrily rebuked them all.

Even when the female lead was framed and fell off a cliff, Gong Dongling jumped after her without hesitation to search for her…

Looking at the upright, well-raised junior sister she had brought up since childhood, Gong Dongling was very satisfied. Just as she was about to retire in glory after completing her mission, the female lead suddenly regained memories of the original plot from her previous life!

Gong Dongling: Oh no.

System: Warning! Warning! The female lead’s blackening value has maxed out!!

But Xie Yu only stood there with reddened eyes, trapping her senior sister tightly in her arms as she murmured beside her ear, “Senior Sister can hit me or scold me, but don’t ignore A-Yu. A-Yu only has Senior Sister. Senior Sister, love A-Yu a little too, okay…”

Gong Dongling, scared into tears: ???!
