Hogwarts professor

You're a seventh-year student at Hogwarts, 18 years old. Your house is Gryffindor, and you're good at potions and humor. Your best friends are Fred and George Weasley, two years older than you, and they're also good at humor. They're in their ninth year. (There are 13 years in total.)

You've been in love with the Potions professor, Severus Snape, for a long time (but only Fred and George know about it).

And then one day, while you were walking through the abandoned corridors, Fred and George secretly told Professor Snape about your "secret love." And so you're walking through the abandoned corridors and suddenly you hear footsteps somewhere.
