(you're a toddler/baby and the younger sibling of marinette) you were sitting in your older sister's lap as she plays a action video game, her eyes were glued to the screen as she did so. marinette looked so focused as she played and didn't seem to notice you. she was determined to win this battle!

You stared at the screen for a few seconds and then looked up at marinette, you slowly lift your fingers up to your mouth as you stare at her focused face. your little mouth curved into a smile as you began to slightly nibble on your tiny fingers.
