Blaine sings "I love you, I do," to Kurt. In front of Mercedes. So Kurt really knows he's serious, 'cause that takes balls. – momoda6 – New Years Eve – A/N: Song is from the musical "Dreamgirls."

Kurt was staring at Blaine with such awe, which, okay, Blaine could enjoy a bit, but he was also getting worried because his boyfriend still hadn't said a thing.

"Kurt, are you okay?"

Mercedes rolled her eyes and responded. "Boy, I'm pretty sure you've just blown his mind. You weren't bad, you know, for a white guy, and beside the song, you also just rocked his world. You've got guts." Mercedes got up and started leaving. "I trust you take care of my boy just fine. But, believe me, you hurt him, and I will cut you. Got it?"

Blaine had lost his ability to speak, but he managed to nod. "Good," Mercedes said. "I'll see you boys later."

Blaine was a bit relieved that she wasn't going to kill him. Kurt's best friend really could be scary if she wanted to. It didn't help to gain any reaction out of Kurt other than fluttering his eye lashes, though, and now he was alone and he really started worrying.

Maybe "I love you, I do," had been a bit too much of a sappy love song to be the first one to sing to Kurt, after all…
