Rebirth

Archmage gets reborn as the princess of a kingdom where she makes everyone fall in love with her cuteness. She tries to keep the peace and discover how she was caught and reborn in the first place all whilst keeping alive from enemies.

MC is seeking love from her noble father who picked her off the streets and so she keeps a quiet life until she is shipped off to marriage and he kills her only for her to be reborn/go back in time. Now she tries to live life how she wants although her father keeps her on a tight rein.
She meets with a black knight who slowly opens up her world in exchange for her help to decipher ancient texts which will lead to....?

Reborn as an orphan, gets sent to palace to work as a maid/poison tester. Becomes a favorite of the saintess (whom has same hair color) and the king (which she has a pain reliever effect on). Also gets into all sorts or trouble so far.

FL used as a replacement for a duke's daughter, goes on to marry the king and have a child before the real her shows up to take it all from her. She dies and goes back in time where she decides to play the players.

Interesting to see how she's going to turn the tables without being burned.

Taken back in time by a goddess who was entranced by her voice, MC tries to protect her family and discover who it was plotting their downfall while also ensnaring everyone with her cuteness overload.
