Remus always knows...
James rambling about who he's falling for, and everyone thinks it's Lily until he slips up and says "he" and Regulus, who had been desperately ignoring it looks up at him. Just in time to see James go crimson and run away
"-just so fucking perfect, you know?"
James Potter's voice carried through the stacks of the library as Regulus paused, listening intently from his now-hiding space, staring at the words on his open book but not taking in a single syllable.
"I just...I feel like I'm invisible. Like no matter what I do, I'll never be worthy. Like, why is it the one person I fancy just thinks nothing of me, Moony? Like...just looks right through me?"
Regulus snorted a bit, unable to hear Remus Lupin's much quieter response. Of course Potter was still waxing poetic about Evans. of course he couldn't let her go. Of course.
"I know, but I just- there's nobody more amazing! So...smart, and...and gorgeous!"
More murmuring, then some shuffling as Potter and Lupin sat at a table nearby, now within Regulus's line of sight. He stared more intensely at his book, still listening closely.
"No, I...Moony, it's not just a crush. I can't even describe how I feel. Like, whenever we look at each other...I'm just...I just feel better, you know? Like I'm like light or something. It's so stupid and cheesy, I know, but I just..."
Potter's voice trailed off and Regulus chanced a glance up to see the taller boy also looking at him. Feeling himself go red all over, he quickly looked back at his book, feigning indifference.
But then Potter continued, his voice airy and distracted, as if he was almost drunk.
"Merlin, he's just so beautiful."
And at that, Regulus' couldn't help but glance's eyes snapped back up to meet James's. Because the words seemed to come from James's mouth quite without his permission. And both of them seemed to realize at the same time that James had said 'he.'
And then, before Regulus could react, James turned bright red and stuttered something about Quidditch practice before running off, leaving Regulus to stare incredulously at Remus.
"....Well. He's clearly not talking about Lily," Remus grinned, smirking at Regulus and walking away.
