Jung Ae secretly asks her friend for help to find Dong Gu, and her children, Eun Hyuk and Eun A. Eun Sung finally gets a chance to perform on stage for the first time after joining the theater. While Eun Sung practices the role at the park, Sun Woo happens to see her acting.

Following an unexpected response to her soft-spoken words from an invisible presence, Eun Sung hurriedly leaves the park. Meanwhile, Ha Young sets her sights on Sun Woo as a potential boyfriend. As fate would have it, they cross paths, and her scarf accidentally drops in Sun Woo's path. She regards this as an ideal, coincidental moment to initiate their relationship and excitedly anticipates his gesture of picking it up.

Eun Sung crashes into Sun Woo dressed in a cat costume, and a mob of people start taking pictures of her because of her outfit. Sun Woo, who sees her hesitating about what to do, covers her up with his jacket. However, she runs away without saying a word. Later, Sun Woo reports her to the police, hoping to get back his jacket with his wallet and phone.

Eun Sung talks to Si Heon to persuade him to withdraw his complaint. However, with Ju Ri by his side, Eun Sung has zero chance of getting out of this trouble. Ha Young finally meets Sun Woo in person at the office and already makes an unpleasant first impression.

With Sun Woo's help, Sun Ju posts the truth behind Si Heon on the Internet for Eun Sung. As expected, Si Heon cannot handle the criticism and resentment toward him.

Managing to fix Ha Young's shoes, Eun Hyuk returns them to her. While Eun Hyuk imbues each moment related to the shoes with meaning, Ha Young remains uninterested. Meanwhile, Sun Woo uncovers Eun Sung's falsehood about why she was present at the location of their encounter. At the dumpling place, Dong Gu reminisces about days gone by.

Crossing his fingers that it wasn't too late to figure out who he collided with, Dong Gu promptly searches for Jung Ae. However, in the inevitable way desperate situations unfold, he comes up empty-handed. Meanwhile, Eun Sung's sole focus is on her audition at Cheong Film. Determined to make it happen, she whisks Sun Ju away, seeking a favor.

Towed by Eun Sung, Sun Ju finds herself on the brink of a close encounter with Sun Woo at Cheong Film. Unaware of Sun Ju's odd demeanor, Eun Sung proceeds with her ritual involving a good luck charm. Meanwhile, Chun Young and Yoo Dong Gu face suspenseful moments as Eun Hyuk eagerly agrees to check security footage and identify the person who took the stolen dumplings.

However, Jung Sook also wants to give it a shot.

Eun Sung gets hired as an admin assistant at Cheong Film after a job interview with Ha Young, not knowing she will be working with Sun Woo. Dong Gu is against the idea of Eun Sung joining Cheong Film as an assistant, but she decides to swallow her pride and take the opportunity.

The weight of stress on Eun Sung becomes evident as she struggles to catch her breath upon discovering that Sun Woo is the director at Cheong Film. Sun Woo, in turn, feels a sense of disappointment as he observes her altered behavior toward him in light of this revelation. Eun Sung is eager for the awkwardness to subside and takes the initiative to propose a solution.

While Sun Woo engages in self-encouragement at the park, Eun Sung catches him off guard with an unexpected interruption. Struggling with embarrassment over his spontaneous monologue, Sun Woo hastily provides flimsy excuses. Despite his efforts, Eun Sung perceives his desperation and silently extends a heartfelt wish for good luck. Meanwhile, Ha Young considers approaching Eun Hyuk for crime-related consultations.

Eun Sung happens to find out that Sun Woo is in a difficult situation as she reads a legal document on his desk. Furthermore, Ha Young gives a simple task to Eun Sung, but she ends up losing all the important files of Cheong Film. Meanwhile, Both Ki Seok and Jung Ae get a tip that Dong Gu is in the country.

The moment Jung Ae hears the news about Dong Gu, she wants to start searching for Eun Hyuk and Eun A as soon as possible. However, Jung Sook is the only one who is not happy with the news. Meanwhile, Eun Sung runs around everywhere to restore all the files she lost, and Sun Woo is worried about her.

Eun Sung is supposed to meet a video creator to restore all the lost files, but Sun Woo feels that there is something fishy about this guy. Meanwhile, Eun Hyuk obtains video footage of the dumpling thief, and Jung Sook is hiding something about Dong Gu from Jung Ae and Ki Seok.

Meanwhile, the whole family urges Chun Young to use the cooking class tickets they couldn't sell from the things they got from Mr. Park's items.

Jung Ae and Chun Young see each other in the cooking class and are completely shocked. Ha Young asks Eun Sung what made Sun Woo misperceive her while pretending to have a special relationship with Sun Woo. Meanwhile, Eun Hyuk receives Dal Yong's advice over his thoughts regarding Ha Young.

After reading Eun Sung's delayed text message, Sun Woo sobs by her side as her condition suddenly deteriorates. Meanwhile, Jung Ae and Ki Seok visit Eun Sung at the hospital after worrying about how she severely injured herself by saving Sun Woo, and Dong Gu and Chun Young decide to let Eun Sung be in love with Sun Woo.

Eun Sung regains consciousness, bringing immense joy to Sun Woo. Having experienced the fear of almost losing each other, they express their love freely. Meanwhile, Jung Ae learns of Sun Woo's awareness of their non-biological relationship and wants to have a conversation with him.

After careful thought, Jung Ae wholeheartedly gives her blessing to Sun Woo and Eun Sung's marriage. Simultaneously, Eun Sung's family, alongside Sun Woo and Ha Young, come together to celebrate Eun Sung's recuperation. Meanwhile, Dal Yong and Jin Sil express apprehension about the forthcoming arrangements concerning Ha Young's baby.

Chun Young and Dal Yong's differing opinions on Eun Hyuk and Ha Young's post-marriage residence put Jung Ae in a difficult position. She also has her own ideas on the matter. Eventually, Eun Hyuk and Ha Young feel compelled to go along with Jung Ae's suggestion of living independently on their own.

With Sun Woo's proposal, the two families meet together and agree on having a wonderful joint wedding, except for Jung Ae. However, the two couples, Sun Woo with Eun Sung and Eun Hyuk with Ha Young, get excited about their futures. Meanwhile, Sun Woo and Eun Hyuk formally propose marriage to Eun Sung and Ha Young.

Meanwhile, Eun Sung and Ha Young try on wedding dresses in a battle of nerves that ricochets onto Sun Woo and Eun Hyuk, driving them mad.

As the two couples walk down the aisle, solidifying their commitment to a lifetime of happiness together, tensions linger between the parents of the bride and groom, casting a shadow over the wedding hall.

As Hye Yoon watches Ga Ram play at a playground from a distance, she receives a disturbing call from Do Chul. He threatens to reveal all of her secrets to Min Guk in a menacing manner that deeply upsets her. Meanwhile, Sun Woo and Eun Sung have returned home from their honeymoon to Eun Sung's house, where everything now feels new and unfamiliar for her.

Min Guk falls into deep shock after hearing that Ga Ram isn't his biological child. Hye Yoon tells him the truth from six years ago and that she will take care of Ga Ram if he can't accept Ga Ram. Meanwhile, Jung Ae rebukes Eun Sung as her daughter-in-law about the first family dinner for no apparent reason.

After learning that Ga Ram isn't Min Guk's son, Jin Sil interrogates Min Guk for answers and then sobs in agony.

Regardless of its veracity, Jung Ae experiences a sense of shame due to the media's portrayal of an unfavorable incident involving Eun Sung, leading her to harbor minimal trust in Eun Sung. Matters escalate when Sun Woo supports Eun Sung, leaving Jung Ae disappointed. Feeling compelled to resolve Eun Sung's predicament, Sun Woo steps out of the house, taking Eun Sung with him.

Sun Woo, in a fit of anger, vows to move out with Eun Sung if Jung Ae continues to show displeasure at her presence at home, especially after witnessing Dong Gu and Jung Ae argue about Eun Sung.

Ha Young and Eun Hyuk visit Jung Ae's house, and Jung Ae scolds Eun Sung for not bringing the right tea for Ha Young.

After receiving her diagnosis, Chun Young is taken aback to realize that her sole chance for treatment rests on a transplant. Dong Gu reassures Chun Young that things will work out, and they agree it's best to inform their children about the illness. Without hesitation, all three children and Dong Gu opt to undergo transplant screening tests.

Everyone in Eun Sung's family becomes devastated when they all get a negative match to be Chun Young's liver donor. Sun Woo says he will also get tested to be the donor, but Jung Ae forbids it.
