After their agreement is terminated early, Tae Bong asks to "hire" Dalja as his girlfriend. Things start moving a little too quickly for her, however, when he decides to move in with her after giving up his apartment to escape his mother's grasp.
A woman claiming to be Ki Joon's wife confronts Dalja while she is at work and begs her not to steal her husband. Upon finding out that he is married, Dalja fears being labeled a homewrecker so she tries to break it off with him.
While on a date with Tae Bong, he and Dalja get caught up in the heat of the moment while evading some loan sharks. A handsome stranger, Ki Joon, stumbles upon the scene and "rescues" Dalja from from the uncomfortable moment.
Dalja accidentally agrees to hire Tae Bong as her boyfriend for one month after a night of drinking. When she can't back out of the agreement, she reluctantly plays along to make Sae Do jealous after he starts dating another coworker, Sun Joo.
