As a half-blood blessed with innate magical talent, Cecilia enters The Royal Academy of Ermengard on her eighteenth birthday. Lacking a prestigious family background, she finds herself targeted and bullied by the academy's pure-blood faction, led by Eve. During a desperate attempt to escape one of Eve’s malicious pranks, Cecilia stumbles into the office of Professor Lok.
To his surprise, Lok—an arrogant magic prodigy—discovers that Cecilia’s unique magical affinity can miraculously soothe his boiling blood, prompting him to step in and drive Eve’s clique away. However, as soon as the bullies leave, Lok forcibly detains Cecilia and forces her to forge a soul pact with him.
Born into the powerful Sterling family, Lok is burdened with extraordinary magical power that causes him to suffer excruciating soul burn at specific intervals, driving him into uncontrollable, destructive frenzies. As he grows older, not even the most high-born pure-blood mages can ease his agony, and the threat of catastrophic destruction escalates by the day.
Witnessing Lok’s torment firsthand during one of his episodes, Cecilia’s innate kindness compels her to agree to the soul pact. As they navigate life together at the academy, the shared emotional link created by their bond begins to draw their hearts closer. All the while, the truth surrounding Cecilia's hidden identity gradually begins to unravel.
