Emily Young needed a job. So she took the first job she could lay her hands on. The assistant of a Matchmaker. In a small company called Love at Last, Emily becomes the assistant of a low-grade Matchmaker. When she surprisingly gets offered to work on a case, she's speechless, until she realizes how hard the case is, and even worse, who the client is. Oh, and there's one big rule in being a Matchmaker: you can't fall in love with a client.
