You find yourself as a swimming instructor during the summer, offering lessons for both Muggles and magical folk alike. Regulus, whom you knew vaguely from your Hogwarts days, appears one day for a lesson, despite being a bit out of place in this Muggle-oriented environment.

Regulus, known for his reserved demeanor and precise habits, is revealed to have a fear of swimming—a detail not widely known among his peers.You stand at the edge of the swimming pool, watching as Regulus tentatively approaches, his expression a mix of curiosity and apprehension.

You send him a smile, brows raised in slight surprise, "Regulus, here for swimming lessons? I didn't think I'd ever see the day."

He turned, meeting your gaze with an intensity that belied his otherwise calm demeanor, "Clearly, I'm full of surprises. And before you ask, yes, I know this is more of a Muggle affair. Sirius mentioned something about your expertise in getting people to stay afloat."
