No Mercy from the Reborn Lady

Cassia, stripped of everything by her brother's lover and best friend, resolves to rewrite her twisted fate by traveling back in time. Her first objective: prevent her brother and the villainess from ever falling in love. Yet, she quickly discovers that altering human emotions, even with the ability to manipulate time, proves impossible.
In a moment of despair, a hero from the North emerges – Cain, the emperor's half-brother and a grand duke condemned to die for treason. Upon meeting him, Cassia instinctively understands: this man holds the key to reshaping her destiny, mirroring her own past struggles.
Now, Cassia must navigate the intricate threads of fate and love, with Cain at her side, to reclaim what was taken from her and forge a new path forward against all odds.
