While serving dinner for Gu Il Hoon, Gu Won, Chairman Han, and Han Yu-Ri, Sa Rang picks up Won's plate, puts it in her tray, and then drops from her hand the plate she'd just put in the tray.
At the end of this episode, Sa Rang and Guwon are sitting at the back of her apartment on the second floor in front of a bay window. Someone is spying on them from down below on the street and taking pictures. Yet the pictures he's taking are straight on as if they are being taken from the same level which is impossible.
