You're Six!

You were painting, bored, as you had nothing else to do. In the middle of painting a tree, Nine shows up. They run over to you, and place a pink bow on your head.

You look up, to see the pink bow, and raise an eyebrow. Nine thought it looked adorable.

You were confused and flustered. The two of you were pink-faced, Nine's being lighter than yours, due to being the person who didn't get a bow placed on their head.

For some reason, the flusteredness gets the better if them, and they pick you up bridal-style. The two of you getting pinker by the second.
