Survive as the Villain's Cousin

The criminal who appeared in the novel and turned the villain evil! Who would’ve known I would be reincarnated as her? I took a deep sigh and made a resolution. ‘Let’s raise the twins with love to prevent them from turning evil!’ However, after seeing the twins, the villains of this novel, sleeping peacefully in a cradle, I felt healed. ‘Alright. No matter what, let’s all live in the Duke’s house together…’ I won’t care about the novel, and get along with the twins, but the sub-male lead who shouldn’t have gotten involved is starting to get obsessed with me!
