Soohyuk, a pediatric emergency medicine specialist at a hospital in Seoul, only ever passes by A Tasty Meal, a local restaurant of sorts, when it's either not open yet or closed. But one day, he finally passes by when it's open. Yuna, the owner and chef of the restaurant, is frightened when she sees a silhouette of a tall man standing outside her door. When Soohyuk comes in at last, she is relieved to learn he was only drawn to the delicious smell.Taken by the pork cutlet sandwich she gives him as a sample of her cooking, and convinced that her food is the only food in Korea that both tastes good and doesn't make him have a violent stomachache all night, Soohyuk asks her to sell him all three meals, every day. She agrees, and he's grateful to finally have good foot to eat between his long shifts at the hospital. As they slowly get to know each other as business owner and customer, they both find themselves oddly attracted to each other.But Soohyuk's harsh way of speaking and Yuna's fear of men, due to trauma from her past, get in the way of any chance they might have at romance. Until Soohyuk meets Yuna's beloved nephew and notices worrisome symptoms in the young boy, symptoms that could mean he will face an uncertain future. The sudden shift in Yuna's family's life forces her to reconsider what truly matters to her, and take a chance at a love she never believed she would find.
