Jung Ae is living a perfect life with a successful husband and son, and all her friends are jealous of her. However, Jung Ae still wants to find her ex-husband, whom she has been out of touch with for 30 years. Meanwhile, Eun Sung picks up a photo of her father on the street.

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.

After causing a huge scene at the theater, Eun Sung quits. However, she regrets it immediately as she is unemployed now. Meanwhile, Ha Young visits a crime scene for her next movie, and Eun Hyuk heads to the same place after getting a report.

Sun Woo and Eun Sung run into each other at the police station. Even though Sun Woo is looking for the cat lady, he cannot recognize her when she's right in front of him. Meanwhile, Eun Sung is worried she might end up in prison as Si Heon is not willing to withdraw the complaint.

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. Therefore, he calls Eun Sung first to meet up and talk it out. Meanwhile, Dal Yong is about to get a divorce from his wife, and his family is worried about him.

Sun Woo recognizes Eun Sung right away with her phone case. Sun Woo and Eun Sung leave the theater together to find Sun Woo's jacket, which Eun Sung lost. However, they run into another problem, and Sun Woo makes a deal. Meanwhile, Ha Young is disappointed with Sun Woo as he did not show up for the movie.

After finally getting in touch with Sun Woo, Eun Sung's only objective is to return his items. Unfortunately, things are not going smoothly for her. She plans to meet Sun Woo before Eun Hyuk learns more about the girl in the cat costume. Meanwhile, Ki Seok learns that Jung Ae is looking for Dong Gu without keeping him in the loop.

Sun Woo meets up with Eun Sung to get back his jacket but sees her with a male mannequin and gets the wrong idea about her job. Meanwhile, Ha Young becomes furious at Dal Yong after she learns about another divorce he had, and Jung Ae happens to walk by Yoo Dong Gu on the street.

On her way to a bakery to meet with Jung Sook to talk to her about her frustration over Ki Seok, Jung Ae walks right past Dong Gu. Meanwhile, Eun Sung stresses over not getting anywhere in her acting career, and Ha Young tries to blame Eun Hyuk for breaking the heel of her shoes.

Sun Woo and Eun Sung both end up at the movies, watching a film together, though not exactly side by side. They hit it off over a little chat about the movie, bonding over shared interests, until Sun Woo unintentionally touches a nerve for Eun Sung. Meanwhile, Ha Young is laser-focused on getting closer to Sun Woo.

Eun Sung might appreciate a bit of consolation as she anxiously awaits the audition results, feeling disappointed with her performance. Meanwhile, Sun Ju unintentionally overhears her mother and aunt, sparking curiosity about the mysterious guy in their conversation.

Following a less-than-impressive audition, Eun Sung can't shake off thoughts about the stranger who offered encouragement in the park. Yet, upon revisiting the park, Eun Sung discovers her rescuer is nowhere to be found. Meanwhile, Ha Young's dedicated efforts to foster a deeper connection with Sun Woo go all wrong.

Eun Sung coincidentally bumps into Sun Woo while applying for an audition at Cheong Film, and Chun Young learns from Dong Gu that Eun Sung failed her audition and heads over to the theater to see her. Meanwhile, an embarrassing video of Dal Yong exposes what a terrible dancer he is.

Chun Young unleashes her wrath on Eun Sung after learning she got fired from the theater. Eun Sung tells Sun Ju about what happened, and Sun Ju takes it into her own hands to punish Si Heon for what he did. Meanwhile, Dal Yong gets caught sneaking into the house by Ha Young.

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.

It's Eun Sung's big audition day, and she prepares to do her best. However, she runs into a little problem right before the audition. Meanwhile, Sun Ju struggles all on her own to show Eun Sung the extra support Eun Sung needs for the audition.

The whole family consoles Eun Sung after they learn together that she didn't get picked for the role. Meanwhile, Dal Yong hears shocking news from his friend while he waits for the woman he met on a blind date to call. Later, Eun Sung sees a job posting from Cheong Film and contemplates applying. 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.

The CCTV footage reveals Dong Gu's determined pursuit of a woman, intriguing Eun Hyuk. Eun A's visit to the station with snacks prompts Eun Hyuk to share the story, sparking her curiosity. At the same time, Sun Ju surprises Jung Ae while she goes through baby clothes purchased for Eun A and Eun Hyuk thirty years ago. The intense verbal sparring between Chun Young and Jin Sil continues.

After learning Eun Hyuk is the police officer who was supposed to be her movie advisor, Ha Young frets that he won't help her. Ki Seok shows Jung Ae the photo that Dong Gu's acquaintance had sent him, and Jung Sook, who now knows Dong Gu is in Korea, becomes anxious Jung Ae will find him.

After seeing Eun Sung and Sun Woo talking on the rooftop, Ha Young asks them if they knew each other from before. Jung Ae visits the police station in hopes her children may have registered their DNA samples in case they were looking for her. Meanwhile, Eun Hyuk asks Dong Gu about the woman he chased after in some footage he was looking through.

Ha Young becomes distressed over the Cat that keeps in contact with Sun Woo and starts to investigate who the Cat could be. Min Guk and Ga Ram hold a special event for Eun A. Meanwhile, Eun Hyuk drinks with Dal Yong, who feels deeply betrayed by his friend.

Sun Woo hands over the cat heart to Eun Sung, but she gets upset as it reminds her of a bad memory. Therefore, Sun Woo feels awful for messing up her day. Meanwhile, Ha Young gets infuriated as she figures out who Cat was all along. She starts to interrogate Eun Sung and Sun Woo.

After talking with Ha Young, Sun Woo is confused about his feelings towards Eun Sung. At the same time, Eun Hyuk happens to see Ha Young and Sun Woo together and gets a wrong idea about their relationship. Meanwhile, Ki Seok suggests Jung Ae take a cooking class at Royal Hotel, and Dong Gu finds out that his sworn enemy, who scammed him with his money, is staying at Royal Hotel.

Eun Sung becomes upset at Sun Woo for mistakenly thinking something else about her job profession and storms off, leaving him behind. Jung Sook is shocked when she hears the news of Dong Gu's death from the private detective agency. 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.

Eun Sung believes Sun Woo is interested in Ha Young and tries to keep her distance from him. Jung Ae can't get over seeing someone who looks exactly like Chun Young in the cooking class and digs deeper into her identity. Meanwhile, Ha Young offers Eun Sung a tempting opportunity to keep her away from Sun Woo.

Sun Woo is disappointed as Eun Sung did not show up for their dinner date. At the moment, Ha Young joins him just as she planned, but he leaves the restaurant right away. Even though Ha Young feels humiliated, she tries to win him back. Meanwhile, Jung Ae and Chun Young meet again at the cooking class.

Eun Sung finds out the message Sun Woo sent has disappeared, and Ha Young tries to come up with another plan to come between them. Meanwhile, Sun Ju gets extremely drunk and is about to pass out at Dong Gu's restaurant, while Sun Woo visits the park where he met Eun Sung for the first time.

While making her way home, Ha Young's path is crossed by a menacing and intoxicated stranger, but she finds her savior in Eun Hyuk. Overflowing with gratitude, Ha Young earnestly thanks him, but her words inadvertently confuse Eun Hyuk. Meanwhile, at the office, Ha Young deliberately obstructs Sun Woo, preventing him from joining Eun Sung on their location-hunting expedition.

Sun Woo rushes over to protect Eun Sung, who screams out in fear. However, they become trapped in the dilapidated factory in frigid conditions without warm clothing. Eun A hears about Min Guk and Ga Ram's story from Chun Young. Meanwhile, Ha Young calls Eun Hyuk after getting into a fight with Dal Yong.

Jung Ae shows Eun Sung how grateful she is for saving Sun Woo. Ha Young also rushes to the hospital to see Sun Woo after hearing about what had happened. She runs into Eun Sung at the hospital but gives her a hard time for letting Sun Woo almost die. Meanwhile, Ga Ram waits for Eun A excitedly.

Eun Sung and Sun Woo meet at the park and confess their feelings toward each other, while Ha Young visits Sun Woo's home to check in on him. Ga Ram waits for Eun A the whole day even though she cannot make it due to work. Min Guk gets upset at Eun A, and she feels terrible for canceling the plan.

Chun Young barges into her restaurant while Eun Sung and Sun Woo are on their secret first date. Jung Ae and Chun Young have a huge fight and cause a scene after the cooking class. Meanwhile, Eun A apologizes to Ga Ram, and Eun Hyuk gets a gift for Ha Young.

Eun Hyuk becomes flustered when Ha Young asks if he has feelings for her, and Jung Ae finds out that the police officer who kindly helped her was Chun Young's son. Meanwhile, Ha Young becomes extremely jealous when she sees how close Sun Woo and Eun Sung have become.

Eun Sung tries her best to resolve the incorrectly ordered coffee and pastries, while Ha Young meets the CEO and insists that Eun Sung gets fired. Meanwhile, Sun Woo figures out that someone intentionally manipulated the order Eun Sung made.

Ha Young becomes nervous that the security footage will reveal her misdeed, and Sun Ju asks Min Guk's coffee shop for part-time employment. Meanwhile, Sun Woo finds Ha Young's alibi suspicious while searching for the person responsible for sabotaging Eun Sung's order.

Ha Young shares what happened at her office with Eun Hyuk, and he advises her to apologize to her colleague. Sun Ju starts working at Min Guk's cafe and gives him a hard time on her first day. Meanwhile, Ha Young musters up the courage and tell her boss the truth.

Eun Sung has no choice but to introduce Sun Woo to her parents since they got caught by Chun Young. Eun Sung and Ha Young decide to let the coffee truck incident slide, but Ha Young is still upset about Sun Woo. Meanwhile, Jung Ae calls Ha Young to talk to her over dinner, and Eun Hyuk runs into Ha Young at Min Guk's cafe.

After learning about Dong Gu's whereabouts, Ki Seok runs into Eun A while snooping around Haha Chicken. Eun Sung senses something wrong in Sun Woo's expression after he hears about Ed Williams, a famous Hollywood director, visiting Korea. Meanwhile, Ha Young has dinner with Jung Ae alone.
