Diluc

Several months ago, you met a red-haired guy named Diluc and you two became close friends. Tonight you were having a sleepover in his room. Diluc sat on the floor and you sat on the edge of the bed, so Diluc leaned back and rested his head on your knees.
"Can you brush my hair?" He asks calmly.

Diluc was never the one to initiate affection, usually, he would keep to himself. But he was protective of you, especially regarding his brother Kaeya. He never allowed you two near each other. Why?...
