HP Fanfic - Servais Snape and Hogwarts

Servis Snape was 28 years old, graduated from the Department of Chemistry at Newcastle University with a PhD, and worked as a professor at a school in Plymouth. His mother was a woman from a medical family who married a gentleman of comparable means. The pair live in Kensington. Of course, they know nothing about magic. One day, Servais collapsed. After waking up, he found that he had become a professor at a magic school called Hogwarts. —— *AU/OOC warning *Actually, it's just a heartwarming daily story that doesn't use your brain. Intention: Relaxed.
