Because you are a Prince

Chuntao hastened towards the place where Nianzu had told her to wait for her. "I am late. His highness might be waiting for me. How can I be so careless?" Chuntao mumbled while walking briskly. Since night had fallen, the road was not fully visible. She did not see the pebble on the ground and fell. 

She hurt her knee while a low cry escaped from her mouth. A few people who were walking past her glanced at her but walked away. She quickly stood up and resumed walking. Soon, she reached the same place which Prince Nianzu had mentioned to her. She was relieved to see him there, who was sitting under it with a lantern beside him. 

Chuntao halted right in front of him, catching her breath. Nianzu was delighted to see her. "F-forgive me, y-your highness. I got busy with my friend," Chuntao said, lowering her eyes. She stepped ahead and quickly carried the lantern in her hand.
