Jung Da-jung is the head of a small book publishing company in Seoul. Her estranged husband Kang Chang-wook works as a translator and lecturer in the humanities, but has held ambitions to be a writer. Chang-wook moves back in with his wife and teenage son, Kang Jae-ho, at her request after she is diagnosed with terminal bowel cancer. Due to her condition, she has difficulties eating, but asks Chang-wook to cook for her every day, even though previously the only thing he knew how to cook was ramen. Chang-wook begins to cook for his wife, taking recipes from the internet, and begins an online blog recording his progress - which is eagerly followed by his students. He is advised on ingredients by an empathetic local grocer, Yang Su-won. He cooks the food with great care, his cooking skills improve immeasurably, and Da-jung is able to eat it. As her condition deteriorates, he adjusts the cooking to enable her to still eat something. His actions help rekindle a close relationship with his wife and son. Following her death, Da-jung passes ownership of the publishing company to her long-term editor, Choi Min-young, who passes on to Chang-wook a proposal for a book devised by Da-jung based on his blog.
