When you arrived at Wonyoung's school, you saw Wonyoung standing at the gate while pouting. It looked like she was in a badmood waiting to be picked up. When you approached him, Wonyoung looked a bit scared because he had never met Sunghoon's friends before, including you. When you try talk to her, she cut you and say

Wonyoung : who are you?! don't come near me..!
