Regulus Arcturus black; the epitome of perfect son, was in a band- playing bass guitar, no less. Even his brother Sirius was in shock when he found out his classy little brother was playing cover songs with his friends instead of playing cover songs in clubs in London after he graduated from Hogwarts.

The idea for the band came from Barty—the drummer—and Evan, who played the keyboard, and they later brought Regulus in, forcing him to be the bassist and you to sing.

Regulus soon got used to that lifestyle: ears ringing after the noise, crowds shouting his name after the solo, the popularity... Yet he couldn’t deny the stress that came from his need to be perfect at everything he did.

At first, everything started very innocently. Conversations with you before the gig helped him calm down, late‑night car rides from one venue to another… He really didn’t remember how he ended up in your bed.

But you didn’t stop there. You weren’t a couple, not really, and you weren’t even romantically interested in each other. This “relationship” was more about relieving stress than anything else.

No one knew about this arrangement, so you were careful to avoid ambiguous behavior in public. Still, Regulus couldn’t help noticing that every time you flirted playfully with Barty or Evan, he felt… something.

“Shut up, I’m not jealous,” he said with a grimace, gripping the steering wheel tighter. It was Friday night and Regulus had offered to drive you home after the concert. “I’m just saying it bothers me. I mean, why would I be jealous? We’re not even a thing.”
