A girl without magic trying to become a witch finds her master in a talking black cat cursed to stay feline unless someone kisses him. The show builds its entire premise on mutual desperation dressed up as a deal, which means every lesson is actually foreplay, every magical failure is a setup for him to catch her, every moment suspended between "this is ridiculous" and "wait, is this actually happening." The romance doesn't arrive later, it's baked into the setup so deep that watching her stumble through spellwork while he corrects her has teeth to it, a constant low hum of tension that never lets the comedy be just comedy.
Spica Virgo dreams of attending the most prestigious magic academy in the kingdom, but there's one problem: she can't cast a single spell. Without a master to vouch for her, admission is impossible. Broke and desperate, Spica's life changes when a sleek black cat suddenly appears with the ability to wield magic. The cat strikes a bargain. He'll teach her everything she needs to know if she helps break an ancient curse binding him to his feline form. The catch involves something neither of them expected: the cure requires physical affection, specifically a kiss. What follows is a chaotic partnership between an earnest but clumsy apprentice and a sarcastic magical mentor navigating classroom politics, dangerous spellwork, and the awkward reality of their arrangement. As Spica slowly improves her abilities and gains confidence, deeper secrets about the cat's past and the nature of his curse begin surfacing. Their unlikely bond grows stronger with each lesson, challenge, and stolen moment, turning what started as a transactional relationship into something neither anticipated.
