Work Text:
John is halfway up the stairs to 221B when violin music reaches his ears. He lets himself in the door to the kitchen so as not to interrupt and sets the paper bag in his arms down as lightly as possible. The song is bright and bouncy, and John can see Sherlock swaying along as he works the bow. It certainly makes putting the groceries away much more enjoyable.
He is heading to his armchair when suddenly the tune sinks in as familiar. John’s brow pulls into a furrowed ‘V’ as he tries to place it. He isn’t the most literate in orchestral pieces, so he feels wrong-footed having recognized something that hasn’t been featured on Looney Tunes or a car commercial. Sherlock peeks over the shoulder holding the violin briefly and smirks at the sight. While it looks like John is furiously scowling, Sherlock knows that to be John"s “can’t figure out a puzzle” face.
John finally snaps up his head, lyrics flooding into his mind.
...I wanna be that guy
I wanna kiss your eyes
I wanna drink that smile...
“Seriously, Sherlock? Ed Sheeran?” John laughs.
“You"ve been humming it while washing up, and it got stuck in my head!” He retorts with feigned disgust. Sherlock winks at John mischievously, finishing the song with a flourish of his bow.
