The story of Elera begins as the Christmas season arrives, promising a joyful reunion with her longtime, long-distance boyfriend, Jake. She has spent the last six months intensely focused on her studies at the prestigious Greenlish Academy, keeping her relationship with Jake alive through distance and devotion. However, Elera's excitement for the break is clouded by the unwelcome attention of Dexson, an ultra-wealthy, enigmatic student at Greenlish. His gestures—lavish, unsolicited gifts, and calculated encounters—make her feel less courted and more deliberately stalked. Still, she dismisses his motives and heads home, eager to fall back into the familiar comfort of Jake’s arms. Elera’s world shatters just days into the holiday. She finds Jake in bed with another woman. Her entire foundation of love and trust is utterly destroyed by this devastating betrayal. Returning to Greenlish Academy reeling from the trauma, Elera makes a drastic decision: she accepts a contract relationship with Dexson. Driven by emotional numbness and a desire for protection (or perhaps, revenge), she uses the wealthy student's interest to shield her broken heart, believing she can control the terms. As the façade wears on, a more complicated reality emerges. Despite her best efforts to remain detached, Elera finds herself slowly, gradually developing genuine feelings for the calculated, possessive Dexson. The Despair and the Twist... The emotional pressure builds until Elera reaches a breaking point, haunted by her past joy and feelings of self-guilt over the destruction of her relationship with Jake. After learning that Elera is pregnant—but with Dexson’s child—Jake crumbles completely, refusing to accept the fate of their ruined love. Consumed by despair, Jake attempts to commit suicide but is barely rescued, left fighting for his life. It is during this crisis that the devastating truth is finally revealed. One of Elera’s jealous classmates, a rival of Dexson’s who sought his attention, orchestrated the entire betrayal. The girl drugged Jake during the Christmas period and falsely staged the scene to appear as if they had sex. She confessing in a mocking grin to Elera that she never actually slept with him—the drug simply made him pass out, framing a non-existent infidelity to utterly destroy Elera’s world and clear the path to Dexson. The twist leaves Elera alive but emotionally shattered, realizing the sacrifice she made was based on a manufactured lie. Meanwhile, the real victim of the drugging and betrayal, Jake, is left in a profound coma, physically and mentally unable to accept his horrific fate, leaving Elera tormented by guilt and unanswered questions.
