The Baby Paves A Flower Path On Her 4th Life

Elia, Guardian of the World Tree.
After experiencing three regressions, she’s on the verge of ending her fourth life—
when she’s unexpectedly saved by none other than Duke Cartellani, the man who was the first to die by her hand in the past.
But there’s one problem with this noble house: they’re incredibly poor.
Thanks to a generous head of the family who gives without holding back, Elia, out of guilt and a desire to repay the favor, decides to stay and help.
She gives them land that can produce food, earns money for them, and is ready to leave…
…when the First Prince—who was the second person she killed—arrives at the duke’s estate for recovery.
To make amends, she cures his illness and restores his health.
That’s when a new crisis hits the duke’s household.
“When will I ever get to leave?”
At this rate, she might just get too attached to walk away.
Elia who wants to die, and people determined to stop her.
Will Elia ever get what she truly wants?
And what is it that the World Tree desires from Elia?
