Joon-ha is to go on a 5-day business trip to China. On the night before he leaves, Hae-mi speaks of the time when she once went for training to the United States and Joon-ha terribly missed her, but finds Joon-ha falling asleep on her. Meanwhile, Yoo-mi comments how she loathes Hye-mi and that she won’t let it go if Hye-mi ever annoys her. Then, Hye-mi accidentally bumps into Yoo-mi in the hallway.
