First Day Mystery

Shiro feels the cold breeze as she walked into the large and dilapidated gate of her new school. There are two men in black tuxedos guarding the gates. She smiled at them, but she got ignored by the two as they rolled their eyes at her. She felt embarrassed by their sudden action and turns away from them. 

When she entered the academy, she is exposed to a few students scattered in the halls. They're all wearing the uniform, while she is wearing civilian clothes. She was delayed in making her uniform, so now, everyone knows that she is a transferee. 

But what she did not expect is that she had not traveled around the entire academy when someone approached her. She's smiling at Shiro as if she wants to be friends with her.
