Villainess engagement with Prince was broke off. But as the King fainted, she remembered the memories of a nurse. Time to save a life!
Only 3c classical shoujo isekai but seems ok. She faked bullied the MC even before the memorie in order to avoid a civil war. Her basic self was already smart and kind. She basically will cooperate with the 2nd prince to protect the kingdom in the shadow. I’ll wait for more before judging...
