Ilya is trapped in a repeating cycle, reliving the same events without altering her fate. Despite her efforts to change the outcome, her fiancé, Soleil, inevitably grows to love Sylvia, Ilya’s gentle and frail younger sister, leaving Ilya alone. Initially, she tried to influence Soleil’s feelings, which only led to resentment. Later, she attempted to distance herself from their relationship, but her affection for Soleil remained unchanged. The emotions shared among the three remain consistent across each cycle, mirroring the original timeline. As a result, Ilya experiences unending despair, her heart repeatedly broken as she is forced to relive the same painful sequence.
