How to Stop My Villainous Senior Brother from Turning Evil

Si Shao transmigrates into a book, becoming the vicious female supporting character, the white moonlight's substitute.

In the book, after the white moonlight is reborn, the original character sets out on a path of self-destruction and becomes a stumbling block in the romance between the male and female leads.

The last time she tries to sabotage them, the villain, who loves the female lead, kills her with a single stroke of his sword. She falls off a cliff and dies a gruesome death.

To stay alive, the System tells her: You have to follow the female supporting character's plotline and sabotage the relationship between the male and female leads.

Si Shao: Fine.

System: You also have to stop the villain from turning evil.

Si Shao: ...Why?

System: Because he'll eventually destroy the world, and nobody will survive!

Si Shao: ...Fine! I'll do whatever it takes to stay alive!

So Si Shao diligently follows the plot while keeping an eye on the villain at all times to make sure he doesn't grow even more evil. She also has to guide him onto the right path.

Later, she reaches the part where she's supposed to fall off a cliff

As she hangs in midair, she thinks she'll follow the plot to the end. But then a figure in red comes sprinting toward her like a madman, wrapping both arms around her and falling with her...

When she finally finishes her mission and is about to leave

He tugs at her sleeve, eyes red-rimmed, looking both aggrieved and wronged as he gazes stubbornly at her. "I've become a better person. Are you going to leave me now?"

*Lively, adorable little fairy x red-clad, lovesick, monstrous beauty

#My lovesick senior brother has gone even crazier since meeting me#

P.S.

1. The original male and female leads are not villains.

2. The male lead has no romantic involvement with the original female lead.

3. Lovesick, deranged, and a story of redemption.

Theme: If you want to stay alive, you have to be strong.
