People wonder why live in such a big building? Seulgi simply answers because you meet alot of people when you wait in the elevator. So when Seulgi meets a girl with round glasses, poinytailed hair, with a cute sweater. She knew that she was going to love waiting in the elevator.
Seulgi walks up quickly to the opening elevator as she is almost late to her work and it wasn't until when she presses the ground floor button and and the door closes did she notice that there was another woman inside as well.
