Se Kyung and Shin Ae live in the deep woods of the Taebaek Mountains with their dad. After going through twists and turns, the sisters finally set foot in Seoul. Will Se Kyung and Shin Ae be welcomed in Seoul, the city of dreams? Everything is so new to Shin Ae, but Se Kyung is too afraid to do anything in this unfamiliar land without their dad.

Se Kyung and Shin Ae are all by themselves in Seoul without their dad. To keep the promise they made to their dad, the sisters head to the N Seoul Tower. But while on their way, they lose all of their money. Meanwhile, Soon Jae and Ja Ok come to a crisis of being caught by the students.

Hyeon Gyeong is extremely suspicious about whether her father is in a romantic relationship with the vice-principal. Meanwhile, without getting to eat anything at all, Se Kyung and Shin Ae endlessly wait for their father, who doesn't seem to come for them.

Shin Ae and Se Kyung manage to find a place to stay temporarily, thanks to Julien's kindness. Meanwhile, Jung Eum becomes Jun Hyuk's tutor to pay her credit card bill, but she soon realizes that Jun Hyuk is the worst student that any tutor can ever have.

Soon Jae promises Ja Ok that he'll be there on September 11 for her birthday. However, he can't help but feel uneasy. He tries to remember what's on that day, but it just doesn't come up in his mind. Meanwhile, Se Kyung leaves Julien's house as she doesn't want to be more nuisance to him.

Bo Seog notices Soon Jae is in a relationship with Ja Ok, but he promises to keep it secret. However, Hyeon Gyeong suspects something is suspicious after witnessing Bo Seog acting awkwardly. She is determined to find out what he is hiding about Soon Jae, so she starts to ask him questions. Meanwhile, Shin Ae gets lost, and Se Kyung searches everywhere for her. She feels devastated because she can't find her, so she asks for help from other people.

Jun Hyuk suddenly gets a high score on his English test, and his teacher at school suspects him of cheating. Jun Hyuk tries to persuade him that he didn't cheat, but it's hard for the teacher to believe his words. Meanwhile, Hyeon Gyeong tenaciously tries to find out the truth about Soon Jae's relationship with Ja Ok. Soon Jae desperately tries to hide the truth from her as he knows she'll bring up her late mother.

Soon Jae's family members are disappointed in Soon Jae for his lies and behaviors, but he just can't give up on his love for Ja Ok. Meanwhile, Se Kyung happens to run into Ji Hoon once again while struggling to get used to her new work at a gas station.

Se Kyung begins working as a live-in housekeeper for Soon Jae's family after some tough difficulties, but Hyeong Gyeong isn't so happy about the idea of hiring her. Meanwhile, Shin Ae is frustrated that she has to put up with Hae Ri's mean attitude.

Soon Jae can't accept the fact that Ja Ok wants to break up with him. So he waits in front of her house until she comes out to meet him despite the heavy rain. Meanwhile, Jung Eum asks Ji Hoon to give her a ride to a subway station and ends up going to Sokcho with him.

Soon Jae gets his love back, but he catches bad flu from getting rained heavily. Hyeon Gyeong asks Se Kyung to make some pine nut porridge for Soon Jae, and she makes it with the millstone which once belonged to Hyeong Gyeong's late mother.

Jung Eum becomes famous overnight. But rather than being excited about it, she quivers with rage. So she comes up with a plan to get revenge on Ji Hoon. Meanwhile, Ja Ok and Hyeon Gyeong share a room on the school staff retreat. But before going to bed, Ja Ok shocks Hyeon Gyeong.

For Julien's birthday, Se Kyung and Shin Ae try to get him a gift. But since they don't have enough money, they ponder what to give him. And at last, the sisters come up with something! Meanwhile, Soon Jae's name was misspelled on his new nameplate due to Bo Seog's mistake.

Soon Jae is excited to go out on a date with Ja Ok. He is enjoying a meal with her in a restaurant when a server there mistakes him for Ja Ok's father. He suddenly feels he has to make an effort to look young to date Ja Ok, so he goes to a cosmetic surgery clinic. Meanwhile, Hae Ri gets a dollhouse as a present from her relative. Shin Ae is jealous of her and wants to have a dollhouse too.

Se Ho falls for Jung Eum the moment he sees her with her hair wet. He starts to daydream about her and even makes a bold move. Meanwhile, Bo Seog fails to close a deal with a client because he forgets to go to the meeting. Soon Jae gets angry and even says he shouldn't have let Hyeon Gyeong marry him. Feeling hurt, Bo Seog leaves the house and doesn't answer Hyeon Gyeong's phone calls. She goes out to look for him, reminiscing about the past when she dated him.

Hae Ri and her friends pick on Shin Ae for not attending school, so Se Kyung tries to send Shin Ae to school. But preparing for school is not so easy. Meanwhile, Soon Jae and Ja Ok run into Julien. Julien greets Ja Ok in the American style, but it seems too friendly to Soon Jae.

Jun Hyuk doesn't like Jung Eum, so he gets her fired. However, she reacts to it with a calm attitude. Jun Hyuk is supposed to be happy that he will no longer see her, but he feels uncomfortable for some reason. Meanwhile, Bo Seog admires Ji Hoon's intelligence. He prevents Ji Hoon from getting injured by getting hurt himself.

Childish and petty confrontations start. Ja Ok and Hyeon Gyeong engage in a war of nerves, which leads them to exact revenge on each other in a ridiculous way. Meanwhile, Jung Eum goes on a blind date, hoping to start a relationship. She gets excited to see that his date is a handsome guy. The date seems to go smoothly, but she encounters an obstacle.

Everyone should be happy as it's Chuseok. However, Se Kyung and Shin Ae become despondent because they can't help thinking about their dad. Meanwhile, Hyeon Gyeong is not happy either because Chuseok reminds her of an incident that happened five years ago. She wants to forget about it, but she can't. Bo Seog is restless and uncomfortable as she is feeling angry.

Se Kyung receives her first salary, which makes her and Shin Ae excited. However, Jung Eum is in a dire situation, so she borrows money from Se Kyung. Se Kyung finds out that Jung Eum doesn't have a good track record when it comes to paying the borrowed money back, so she starts to take drastic measures. Meanwhile, Soon Jae accompanies Ja Ok to a get-together she goes to regularly. He rides a bicycle to the get-together as Ja Ok finds cycling sexy, but something unexpected happens!

Meanwhile, Soon Jae visits Ja Ok as she is sick. While they have a good time drinking tea, someone else comes to Ja Ok's house.

Bo Seog can't do anything right as usual. Soon Jae and Hyeon Gyeong boss him around, telling him what to do and how to do it. Then he hears from Se Ho and Shin Ae that he has no authority in his house and is treated poorly by his family members. He decides to take measures to correct this. Meanwhile, Jun Hyuk goes to see a musical with Jung Eum with complimentary tickets he got from Soon Jae. Surprisingly, Ji Hoon and Se Kyung are also there to see the musical!
