The series is about a mysterious man who works in an airport and he meets Han yeo rum who wants to be the best employee but messes things up. They both start working together in the same department and as their relationship progresses the mysteries starts to unfold.
The series starts in a mystery mode then it transcends into romantic comedy and the final three episodes were the best of all. There were a lot of good elements in this series, Choi soo bin being the eye-capturing one. The rest of the cast also did a good job but it could've been better, especially the chemistry between the lead couple. The second lead couples should have been given a little more importance. The ost was good and there were some emotional scenes as well. Overall it is a good series but could be made better.
