Adrien laid with Marinette curled up against him, the couple watching the stars above them, and he smiles to himself. "This will be an amazing story to tell."

She looks up at him, "to tell who? That Ladybug and Chat Noir laid on top of a roof watching the stars together?" She grins, and he shakes his head, "no. Not to just anyone like you're thinking. To someone important."

Her mind went to Chloe, and she stops smiling, and looks away, "m'lady?" He looks down at her, and she was looking off to the side, "would that important person be Chloe?" She asks, and he gives her an incredulous look, "no. Not her. Someone younger."

"Mano?" She asks, and he grins, shaking his head, "nope. She'll have black hair and green eyes."

Marinette raises a brow, "you've lost me, kitty."

He grins wide, and pecks her forehead, "she'll be the one other girl I'll ever love as much as you." Marinette looks surprised, and he smiles, "I've spent a life chasing stories to tell when I'm old, and my greatest story, I know, will be you, and when she asks about you, I can sit her on my lap and look up at my greatest story, and grin, because you will always be my happy ending."

She finally got it, and giggles, her face flushing under her mask, "you silly kitty..." she says in between giggles. He presses a kiss to her face, and he could feel the supposedly fake tail of his wrap around her legs, "my bugaboo."

She cranes up her head and kisses him softly, "and she'll call you papa." She whispers after pulling away, and he nods, grinning brilliantly.

((I have a theory that because Plagg actually has a tail, and Chat has a tail, that Chat has sensations of a real tail, and can actually get it to do what he wants it to. Hence why he always rubs his tail after Ladybug pulls on it.))
