Charles when you were talking to Raven.

You and the other X-Men were in the mansion just hanging out. You and Raven were talking and laughing. You didn't notice Charles staring at you, a smile on his lips.

"You've got it bad." Alex laughed at Charles, who rolled his eyes.

"Charles is staring at you." Raven whispered, laughing. 

You looked over, and sure enough, he was staring at you. You sent him a smile which made his heart flutter.
