I Mistook the Villain for the Male Lead and Raised Him

After accidentally transmigrating into the vicious female supporting character destined to have the male lead pierce her heart with one sword and scatter her soul, Su Wanwan reflects on her mistakes and decides to bring him home and raise him while he's still a bullied child. With that debt of gratitude, the male lead won't dare lay a hand on her, and he'll have to obediently hand over all his opportunities!

But when she gets there, she finds three equally pitiful children, and can't tell which one is the male lead. So she simply brings them all home to raise. She diligently practices the art of keeping things fair: teaching her eldest disciple swordsmanship in the morning, taking her second disciple out on adventures in the afternoon, and telling her third disciple stories at night. She does her best as their master and never favors one over another.

But none of the three disciples is satisfied. They fight openly and covertly every day, using all sorts of tricks to compete for her favor. Su Wanwan is busy balancing the relationships among her three disciples every day, while also trying to figure out which one is the male lead!

The more she watches them, the more it seems that none of the three is the male lead. Su Wanwan panics and goes to great lengths to find the male lead and bring him home to raise...

And then all three disciples turn dark...
