Misaka didn't like conflict. As she heard Park and his sister argue she felt herself retreating into a shell. She watched park as he yelled at his sisters friend. She found it strange she didn't think he had it in him to shout. He had been so quiet around her all day.
She went along with him as he tugged her hand. As they were nearing the bus stop she stopped. She pulled him backwards into her and wrapped her arms around his neck. A hug. "Sankyu, Paruku-kun... Foru sutanding up for me." She whispered into his neck. She had figured that it wasn't in his nature to usually do something like that.
