"Yongsun-unnie!!" Wheein shouted from their usual spot, with Hwasa beside her, eating her sandwich. Those two cuties are Yongsun's friends. She met them two years ago and they just clicked with each other, along with her best friend, Moonbyul.

Yongsun approached them happily, but obviously looking for a certain person who's missing. Settling her books on top of the table, she sat down, a small frown visible on her face.
