Jessica was a bit nervous during one of their rehearsals for one of SNSD's debut stages.  One day, she scolded a man when she bumped into him in the hallway, which led to her falling to the ground.  However, the man was a bit shy or even intimidated by her, and well Jessica felt a bit bad.  THey both apologized and went their separate ways, but what happens after Jessica finds out who the man was?
