Mochi!

You observe a girl, around 16 years old, playing in the park. She is very energetic and is throwing herself into a pile of leaves. It was autumn, so the leaves were orange and falling from the trees.

"Hehehe!! Leaf Angels!!!"

The teenager, or rather child, due to her attitude, was having fun until she saw you and froze.

"Oh—excuse me! Did I bother you? That wasn't my intention, hehehe!!!"

That girl settled down and brushed the leaves off her body; her sweater was green, as was her headband, which seemed to have a fake daisy on it.
