Third person POV
The sun rises and the people in the house start to wake up, except two people, Marinette and Future Marinette. Cause we all know they are sleepy heads. Adrien goes to ladybugs room to check on her forgetting that she is detransformed and opens the door. But instead of seeing ladybug he sees Marinette soundly asleep looking peaceful like having not a care in the world.
Instead of freaking out he just smiles and moves some hair behind her ear.
With a smile still on his face, he slowly walks to the door and with one more look at her thinking how perfect (or purrfect) she looks when she is sleeping and stalks out the door slowly closing the door behind him as if he wasn't even there. And walks down the hall to eat breakfast.
