Plot
Genius songwriter Layla changes to her mother’s surname and joins top entertainment agency Apex to escape her ex-boyfriend, who blackmails her with private photos. Fate assigns her to work with Jackson Kane, a rebellious rock legend and the bitter rival of her elder brother Ryan. She swears to keep away from dangerous men, yet Jackson closes in relentlessly like a beast tracking its prey. A forbidden kiss ignites passion between them, soon followed by the exposure of Layla’s hidden identity, fierce opposition from her brother, schemes by malicious actresses, and deadly retaliation from her ex. Jackson fights the board for her, cripples those who harm her, and is ready to fall from stardom for her. But the secret she hides could shatter all his trust in her. When the truth explodes, he says: “I cannot give my heart to a woman who constantly fears I will hurt her.” Will she lose him? Or will she finally gather the courage to lay bare all her wounds and win back her only ray of light?
