However, instead of meeting her end, Alicia’s soul travels back in time to a point before the broken engagement and awakens inside Gilbert’s body, forced to coexist alongside his own consciousness. Realizing that her past self is still alive in this timeline, Alicia devises a plan to protect her former life. She intends to gather evidence of Gilbert’s supposed infidelity so that her past self will willingly sever the engagement before he has the chance to discard her. Yet as she begins her investigation from within his mind, baffling truths emerge. Contrary to his sudden betrayal and swift engagement to Cordelia, Gilbert appears to harbor deep, genuine feelings for Alicia. Furthermore, the true motive behind Cordelia’s murderous actions remains shrouded in mystery. Trapped together in one body, they are drawn into an unconventional and deeply awkward romance where two souls must untangle a web of hidden motives and unexpected love.
