It starts with Joo-won accidentally meeting Yun-seo and Seong-min.However, instead of making a fuss as usual, he wished them all the best and turned to leave.

This strange behavior confused both Yun-seo and the audience.However, it's soon revealed that Joo-won is trying a new tactic suggested by his brother - taking a step back and eventually making a few moves to win Yoon-seo back.He distanced himself from Yun-seo and even moved to another office.

Si-won's next suggestion was to have Joo-won play the “bad guy” role, so Joo-won started refuting every idea Yun-seo came up with.Frustrated, Yoon-seo confides in Eli while eating at her restaurant.Si-won then suggests that Joo-won make Yun-seo jealous, although Joo-won thinks this is going too far.

However, when Yun-seo sees him with another woman, she begins to feel uneasy.The woman turned out to be Mi-jin, who arrived earlier than expected and went straight to Si-won.

Mi-jin brought macarons because Si-won accidentally liked her Instagram post.She took a photo of Si-won and the macarons and posted it online.Si-won was initially angry, thinking Mi-jin was visiting him just to post, but later he felt happy after seeing the positive comments.

Mi-jin apologizes and deletes the photo, which dismays Si-won.However, she soon admitted that she posted because she thought he was cute, which moved Si-won.They posed together again and posted it to Instagram, this time out of love for each other.

Meanwhile, Yun-seo begins to believe that Joo-won has finally let go.She recalls their time together, especially on her birthday, expecting him to surprise her, but Joo-won was nowhere to be found.Joo Won, on the other hand, feels bad for not being with Yoon Seo on her birthday.

Si-won finally gives him the green light to pursue Yun-seo, and Joo-won decides to propose to her.Unfortunately, when Joo-won tries to contact her, Yoon-seo leaves the office early after receiving the news of her mother's death.

We learn that Yoon-seo's mother was just as neglectful as her father, standing idly by while she was abused.After her father died while Yun-seo was in college, her mother came to visit her and tried to pass his debts on to her, but Yun-seo refused.

When Joo-won is unable to contact Yun-seo, he becomes increasingly worried and senses something is wrong.Meanwhile, Seong-min, drinking alone, spots Yoon-seo and joins her.

She opens up to him about her difficult childhood, and Seong-min realizes that Yoon-seo still has deep feelings for Joo-won.He decides to call Joo-won, who picks up Yoon-seo and takes her home to let her sleep, although she leaves without saying anything.

Yun-seo told her brother Ji-suk about her mother's death.He told her not to attend the funeral, but Yoon-seo went to the funeral home anyway, even though she didn't pay her respects.

Knowing how difficult this was for Yun-seo, Ji-suk notified Joo-won, who showed up at the funeral to support Yun-seo.Even though Yoon-seo initially tries to push him away, she breaks down in tears next to Joo-won as the episode ends.
