It’s about two women named Oh Hae Yeong getting all mixed up in each other’s lives because they share a name. The problem is that two women not only share the name Oh Hae Yeong, but they also have the same occupation, which is probably the bigger issue. They both work for large catering companies (or perhaps the same one?), and one Hae Yeong is a team leader while the other Hae Yeong is an assistant manager. Kim Ah Joong is up for the role of the assistant manager.
Then there’s also a man in their lives, who has the ability to see into the future.
