Life is tiresome for Jin-ah, from a bad breakup to a office stressful job. Out of the blue Joon-hee arrives home in Korea after 3 years out of the country.
One of Jin-ah's coworkers takes a liking to Joon-hee which rubs her the wrong way; Jin-a's mom begins to worry because Jin-a isn't preparing to get married like others her age.
Although happy with her relationship, Jin-ah still has concerns about it. At work she gets tricked into going on a business trip that no one else wants to take on.
Setting aside her guilt, Jin-A spends the night at Jun-Hui's place. Back at work after the business trip, she gets called to director Nam's office. (Source:Netflix)
