Love Of My Life

Yn is Freddie's best friend. That's it. That's the plot.
Pretty much at least

"Fred!?", Yn called their singer over the speaker, "Fred! I think that's enough now! It's five in the morning."
"But does it sound good?", He asked back and raised his eyebrows.
Yn had to shake her head and rubbed over her forehead.
"All of it sounds good. Everything sounds good at this point! And it also won't improve now. We've been at it for over 10 hours.", She told them, "Roger's voice is thinning out, Brian's fingers hurt, I'm sporting a grade A headache and I'm sure your throat hurts at least a little bit!"
"True. But does it sound good?", Freddie asked again and Yn showed him thumbs up. With another shake of her head she let herself fall back onto her chair.
