This Time, It's My Turn to Serve You the Poisoned Chalice of Ruin

Adeline, the daughter of the Duke of Montferdi, devoted everything she had to Noah, the fiancé she loved with all her heart, helping him ascend to the imperial throne.

However, one day, she makes a mistake she can never undo. After witnessing Noah's infidelity, Adeline confides in her closest friend, Blanche, unaware that Blanche herself is the woman Noah has been having an affair with. Caught in their carefully orchestrated scheme, Adeline is falsely accused of treason and poisoned to death. But when she unexpectedly opens her eyes, she finds herself in an unfamiliar body. Not only has she traveled five years into the past, but she has also become Priscilla, the daughter of Baron Isete!

This must be a second chance granted by God. With no one left to stand by her side, Adeline swears to take revenge on those who betrayed her.
