From a breakup to work stress, life isn't all that peachy for 35-year-old Jin-a. Meanwhile, Jun-hui arrives back in Korea after three years abroad.
One of Jin-a's co-workers takes a liking to Jun-hui. Jin-a's mom begins to worry because Jin-a isn't preparing to get married like others her age.
Gyu-min goes around saying that Jin-a likes Jun-hui, but no one believes him. Jun-hui seems to think Jin-a wants to get back together with Gyu-min.
Although happily in love, Jin-a still has concerns about her relationship. She volunteers to go 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.
For Jun-hui, keeping his relationship a secret starts to get frustrating. President Jo asks the female employees to bring forth their grievances.
Seung-ho is angry with Jun-hui. Jin-a runs into issues while trying to replace her broken smartphone because the account is under Gyu-min's name.
When no one seems to know where Jin-a is, Jun-hui starts to panic. Worried for her safety, he tries to get hold of Gyu-min.
Refusing help from her dad and Jun-hui, Jin-a plans to break the news to her mom and Gyeong-seon herself, but it doesn't go as smoothly as she hoped.
As everyone predicted, Jin-a's mom reacts rather melodramatically to Jin-a's news, injuring herself and hurting others' feelings in the process.
Jun-hui is more concerned about Jin-a's feelings than his own, and refuses to give up his relationship with Jin-a despite her mom's hurtful words.
With Gyeong-seon and Jun-hui's dad sitting close by, Jin-a isn't able to focus on her blind date, who takes notice and obviously isn't pleased.
Furious at Jin-a, Jun-hui cuts off communication with her completely, which makes her worry. Jun-hui's dad calls Jin-a's dad and asks to meet.
After making her shocking announcement, Jin-a pays a surprise late-night visit to Jun-hui's place. Jin-a is told by her mom to move out of the house.
Jin-a tries to keep her housing situation a secret from Jun-hui. Meanwhile at Jin-a's company, there's much scheming going on behind her back.
Memories of their happy past come flooding back when Jin-a and Jun-hui see each other for the first time in months, but this only adds to their pain.
