“What is it you’re humming?” Kurt’s voice sounds light and playful and as Blaine thinks back over the last few seconds he realizes he was.

Kurt just wanted an excuse to talk to him instead of staring at his French homework but now he’s interested. He stares and waits and then settles back into his essay knowing Blaine will start again. He’s been humming absent-mindedly during their study sessions for weeks.
Sure enough ten minutes later he’s humming as he flicks through a book and stares hard at the maths.
“Blaine,” Kurt says, turning properly to face him. “Humming.”
