Too Late for My Shifters' Regret

Ivy drains herself raising three SSS-rank wolf shifters, only to realize their true desire is her sister, Lilith. She gives them up in exchange for Lilith's cold serpent shifter, Caesar, and to her surprise he grows deeply devoted to her. With her family forcing her toward a risky arranged marriage to a mysterious dragon, Ivy must fight for her place at the magical academy by winning the Spring Competition, while Caesar, now a legendary-class creature, stands with her against Lilith and the wolves she left behind.
