Yang Eun-bi (Lee Chung-ah) is a university student in her mid-20s preparing for her civil service exam with the dream of being a high school teacher. She accidentally encounters Cha Chi-soo (Jung Il-woo), the arrogant heir to the biggest food conglomerate in South Korea. Cha Chi-soo, newly home after a failed attempt to attend school in New York City, fascinates women with his good looks and easy charm. Eun-bi is attracted to him before she finds out that he is only a high school senior and thus several years younger than her. However, her student-teaching assignment finds her not only working at the high school that Chi-soo's family owns, but teaching his homeroom class. She grows to dislike him for his arrogance and lack of empathy. He, on the other hand, becomes fascinated with her because she is outspoken and athletic, unlike the other women he knows. Yet, he does not interpret the fascination as romantic interest, since he is out of her league and usually dates pretty, self-interested girls like Yoon So-yi, a ballet student also dating Chi-Soo's rebellious classmate Kim Ba-wool. Eun-bi resists her attraction in turn, believing Chi-soo is only toying with her. Eun-bi wants a more serious relationship after being dumped by a cheating ex-boyfriend after waiting for him to complete his mandatory military service. She frequently turns to her dating-savvy roommate/ex-high school volleyball teammate Kang Dong-joo for advice.
After Eun-bi's father (Jung In-ki) passes away, she is surprised to find that he left the ramen restaurant he owned to Choi Kang-hyuk (Lee Ki-woo), who he had helped when Kang-hyuk was a troubled youth, instead of to her. It is soon revealed that Eun-bi's father did this with the hope that Kang-hyuk and Eun-bi would marry. Eun-bi, after losing her student-teaching assignment because of her conflicts with Chi-soo, starts to work at the ramen shop, along with homeless fellow students Kim Ba-wool (Park Min-woo) and Woo Hyun-woo (Jo Yoon-woo). Chi-soo wants to work at the restaurant as well, in order to get over his growing obsession with Eun-bi. Kang-hyuk, who knows that he and Chi-soo actually have the same mother, allows him to join the shop out of concern for his cold half-brother.
Kang-hyuk quickly develops feelings for Eun-bi, but she finds herself more attracted to passionate Chi-soo. Chi-soo, after many misunderstandings, realizes that his obsession with Eun-bi is attraction and actively competes for Eun-Bi's affections with Kang-hyuk. However, Chi-soo's father (Joo Hyun) disapproves. Chi-soo's (and Kang-hyuk's) mother had also been an average (not rich) woman, and Chi-soo's father believes that difference was one of the causes of their separating several years before. Chi-soo's father's company is planning to redevelop the area in which the ramen shop is located, and Chi-soo's father tries to use the possible destruction of the ramen shop as leverage to keep Eun-bi and Chi-soo apart. Chi-soo has become attached to the ramen shop and is also afraid of being disowned, and so he initially chooses to stay with his father. Eun-bi realizes, however, that she wants to try seriously dating him; she storms his family's apartment to claim him from his father, and they leave together. The ramen shop is forced to close, but its workers accept this development without complaint. Chi-soo's father disinherits him and has his U.S. citizenship revoked, so that Chi-soo is now subject to the South Korean military draft. The show ends with Chi-soo visiting Eun-bi after he has completed his two-year service in the South Korean Army without contacting her; they kiss as the camera pans over the neighborhood where they first met.
