Hyein, who has been working as a secretary at 'Yoo Seung Precision', a small business, and was fired due to contract expiration, visits 'Yoo Seung Precision', her former workplace, to get a career certificate ahead of an upcoming interview at a large company. However, the real purpose of her visit is to get back the 67,600 won, which the manager Jin Sang-i of the same team has not paid back for running errands for coffee and sandwiches. When she finally arrives at her office, she asks Hye-in Lee to return her money, but she only gets 50,000 won. The only thing she approached the frustrated Hye-in was the (but awkward) Deputy Oh, who was the only female employee on the same team.
