Cast Aside, I Became the Mermaid Princess

After Selene uses the memories of her past life to steal everything from Mira, the girl killed by Selene in the end, Mira returns to the past as well. At Arcadia Academy, the two reincarnators face off in the open and in secret, and Mira outwits Selene at every turn, reclaiming her royal birthright, saving a mysterious phoenix, and finding love with Kael, the prince of the skies, as she takes back the life that was always hers.
