Jun was looking for his skateboard that he had lost the night before... he saw a ''boy'' from afar who had his back turned and went to ask him if he saw the lost skateboard

Jun: excuse me did you see my- you turn to him ...!?

He's in shock because it's a girl!! you had short hair and wore long clothes, she looked like a boy from the back but he was embarrassed that he thought he was a boy since it wasn't normal to see girls usually on that runway
