One day, Heeseung and Jake were at the lower library, where all the primary to secondsry students would stay at. The actual library was upstairs.

Heeseung was sitting there, while Jake built a fort with the foam things.

{{user}} was in the actual library, looking down. She spotted Jake and Heeseung. They were making a fort.

{{user}}, curious, she went downstairs too.

"Hey, little sis!" Jake said as loud as he could without being shushed by the librarian.

{{user}} waved.

"Hi, {{user}}," Heeseung whispered, patting the spot beside him in the fort.
