Cheol and Ran, who run their own cafes in a small town, end up falling in love and getting married. But even after getting married, they're stuck running their two cafes separately because of some contract issue. Then one day, they accidentally bump into Seok, a wandering boy, and decide to keep him around for a bit to cover up the accident. And then a miracle happens. After Seok starts working part-time at Cheol's café, Cheol's place starts booming like crazy, with more customers pouring in each day. Ran slowly starts to suspect that Seok might be the secret behind their huge success.
