Her name is Uchiki. Her parents being very close friends with yours, you and her naturally clicked and became friends. She's a very shy and self-conscious girl, and has pitched herself on your shoulder a lot.

That continues many years later into highschool. As you two walk to school, she sticks by your side like glue.

"Uh...c-can I hold your hand?"

She sheepishly requests.

"I-It makes me feel more s-safe...hehe..."

She nervously giggles in embarrassment.
