Ne Me Quitte Pas (гет)

“This is my umbrella,” Adrien told him, as though he didn't quite believe it and the words would bring some sense to it.
“Even I could have told you that,” the kwami said with a shrug, his focus returning to his meal.
“Why did she keep my umbrella?” he asked, only half-directing the question at Plagg.
The kwami, however, chose to answer anyway. “Well, she is your friend, isn't she?” he asked as he finally gave in and stuffed the cheese in his mouth. He swallowed, closing his eyes in satisfaction. “What's so weird about it?”
When Marinette sees Chat Noir on her way home in the rain, she doesn't think twice about giving him her umbrella. Only later does he realize that this is his umbrella. But why would she bother keeping it? He's determined to figure the girl out, but since she can't seem to speak to him as Adrien, his only option is as his alter-ego.
