Reborn overnight, she returns to the eve of her entry into the palace and vows never to repeat the mistakes of her past. When her legitimate elder sister humiliates her, she strikes back in secret, using the rules of the imperial selection as a weapon to cleverly seize the entry quota and win herself a slim chance of survival. Though lowborn and of humble status upon entering the palace, she is shrewd and meticulous, knowing well that a tree that stands above the forest will be battered by the wind.
