Ikenie Akujo wa Seiteki Ouji no Ban to Naru

When the villainess comes back to life, she discovers that the prince who once hated her is now madly in love with her?!
In this world, “Predators” are the rulers who wield powerful magic, while those born with the “Mark of Sacrifice” are despised as mere wells of magic for Predators to absorb and tools for bearing offspring.
Prince Greg, second in line to the throne, recently rejected a marriage offer from Lady Letishia, a vile Predator. Determined to understand his reasons, she confronts him at the palace—only for both of them to become victims of an assassination attempt, losing their lives in the process. The next moment, Letishia finds herself transported back in time to the day she went to see Greg. Yet, this miraculous second chance comes at a price: she now bears the Mark of Sacrifice.
Imprisoned by her family and facing a future of exploitation, Letishia strikes a deal with Greg, offering him her magic in exchange for his protection. Though they wed under the terms of a loveless contract, Greg seems to have fallen deeply in love with Letishia. But is this genuine love, or is it simply the mark’s influence?
