Reborn as An Lingrong: No Regrets in This Life

After being reborn, An Lingrong enters the palace once more. Having lived through her previous life, she has come to a profound understanding: she lets go of anger and delusion, bears no lingering resentment, and is no longer insecure. She neither fights nor competes, becoming the most inconspicuous consort in the harem.

Later, Yinzhen dies. They say one neglected senior consort has disappeared from the palace, and Jiangnan has gained an embroiderer skilled in making incense.

(A rebirth story with a more realistic approach. If you want a protagonist who humiliates her enemies and slaughters her way through the harem, this isn't for you. Zhen Huan is not villainized, and An Lingrong is not whitewashed. The main theme is making peace with oneself.)
