After a scandal, former idol Ava Chen finds herself at the mercy of her past when she accidentally summons a "Bloody Witch" from a cheap magic book. The witch, with her golden hair and childlike appearance, looks down at Ava and asks, "What do you, a foolish mortal, wish for? Wealth, power, invincibility, or eternal youth?" Ava, however, is more concerned about her attire. As their fates intertwine, Ava must navigate the chaos of her new life while dealing with the unexpected consequences of her summoning.
