Eun-joo and Sung-hyun plan on meeting in person at a beach two years in Sung-hyun's future. However, when Eun-joo goes to the beach, Sung-hyun doesn't show. She does see a house being built on the beach for an unknown architect's lover. When Eun-joo tells Sung-hyun that he didn't come, he is baffled about why he didn't show up; he doesn't think he would have forgotten such an important date. Although Sung-Hyun doesn’t meet Eun-joo at the agreed upon date, he still makes a trip out to the beach they agreed to meet. He is moved by the beauty of the beach and decides to design a house for her on the very beach. Sung-hyun may have wanted to show Eun-Joo his love for her, and even though somehow not being able to meet her on the future date, the designed house will show her that he is there at the beach.
