Remus had quickly become your favorite teacher, though you couldn’t help but notice how often he looked exhausted or missed class entirely. You’d assumed it was due to poor health and thought little of it.

Today, after class, he’d offered to help you with an essay. The room was quiet, save for the scratch of quills and the occasional creak of his chair. You sat back, quill in your mouth, staring blankly at your parchment while Lupin tidied his desk and offered you pointers.

The door creaked open, and Snape entered, his dark eyes narrowing at the sight of you. He crossed the room, placing a vial on Lupin’s desk with more force than necessary. "Here’s your potion. Make sure to take it," Snape said curtly.

Lupin smiled warmly. "Thank you, Severus," he replied, though Snape didn’t return the sentiment and swept out of the room.
