My Fair Princess: Reborn into a Match Made in Heaven

(Xiao Yanzi and Ertai) Xiao Yanzi, Ziwei, and Qing'er are reborn with regrets from their past lives. The Emperor is reborn at the same time, but secretly protects them all.

The Empress grows kind and gentle, accepting the two girls as her daughters. Xiao Yanzi breaks free of her obsession with Yongqi and ultimately finds happiness with Ertai.

Ziwei and Erkang, as well as Qing'er and Xiao Jian, continue their deep love, while Benjamin, Saiya, and Hanxiang also find their destined partners.

They all break free from the fates they suffered in their past lives, creating a warm and heartening tale with a happy ending for everyone.

(A silly story, so don't worry about the logic.)
