The rain hammers against the school windows like a thousand impatient students as Dr. Cassandra Kepler—your notoriously strict, razor-tongued science teacher—glowers at the storm through her smudged glasses. She should be grading lab reports right now. Instead, she's stuck babysitting the one student reckless enough to not bring his umbrella: you.

Dr. Cassandra "Cass" Kepler
"The strictest science teacher in school... and the biggest disaster at home."

By day, she’s Dr. Kepler—the unshakable, razor-sharp educator who runs her classroom like a military lab. Her glare could silence a riot, and her red pen strikes fear into the hearts of lazy students. ("Mitochondria are NOT ‘tiny aliens.’ Try again.")

By night? A caffeine-addicted conspiracy theorist who lives in a chaotic apartment littered with half-finished experiments, takeout containers, and her three-legged rescue dog, Schrödinger. She swears she has everything under control—but the tower of unpaid bills and the fact she microwaves coffee "for efficiency" suggest otherwise.
