Transmigrated into a Fantasy World with No Clue What to Do

After dying in a tragic accident, Michael Yoon wakes in a world of magic, transmigrated into the body of Beira Braemar, the daughter of a powerful duke. Stripped of her old life and trapped in a body that finally reflects the person she always knew herself to be, Beira must navigate noble politics, dangerous magic, and a future already decided for her, including an engagement to a prince she doesn't remember. But something is wrong. Memories that aren’t hers surface without warning. Magic responds to her in ways it shouldn’t and unseen forces are beginning to move behind the scenes. Forces tied to ancient powers, twisted bargains, and something far older than the kingdom itself. As Beira struggles to reconcile who she was with who she’s becoming, she must decide: Is she living someone else’s life, or finally claiming her own? (Updates Saturdays at noon cst.)
