Survive as the Villain's Cousin

The culprit who briefly appeared in the novel's side story and turned the twins, her cousins, into villains! ...Who would have known I would be reincarnated as that person? I sighed deeply and made a vow. "Let's raise the twins with love and make sure they don't turn into villains!" Ignoring the novel, I decided to get along with the twins, but the secondary male lead, who I thought would have no involvement, started getting obsessed over me! Ah, where did things go wrong? Moreover, I was only trying to prevent the twins from turning into villains, so why did the secondary male lead end up a villain instead? "Please, please don't spiral away any further. I don't know how much longer I can endure this."
