Book Transmigration: Is the Chancellor Jealous Today?

Who can tell her what terrible thing she did in her past life? Getting transported into a novel was bad enough, but why did she have to become the villainess who did every awful thing imaginable? The domineering, cold-blooded prime minister wants her dead, the brilliant top scholar wants to poison her, and even her most trusted bodyguard wants to betray her. Sigh. To stay alive, she has no choice but to take shamelessness to the next level, cling to the male lead, and swear she won't be a stumbling block in his romance with the heroine. If she stays as far away as possible, that should do the trick, right? Wait, why did the male lead suddenly confess to her? Weren't you supposed to be devoted to just one person? Weren't you supposed to be deeply in love? She refuses!
