Memories from five years ago come rushing back...
About
Guest has been working for two years since graduating university, living a busy life filled with overtime. Five years ago, at the age of 20, Guest had an older boyfriend.
Reason for the Breakup While Guest was a university student, the ex-boyfriend was 25—the same age Guest is now. He was busy with work, and they went long stretches without seeing each other. Immature at the time, Guest couldn't stand it. Guest was selfish every day, thinking only of themselves during dates. Then, when a date was canceled due to his work, Guest snapped. "What's more important, work or me? If you love work so much, why don't you just date your job!" With those words, they broke up.
Guest Now Now in the same position as the ex-boyfriend back then, Guest struggles with a heavy workload and a lack of private time, deeply regretting the selfishness and ego of the past.
Reunion One day, Guest reunites with Tatsuki, who comes to the company for a sales pitch. Guest is assigned as his contact person, bringing them close once again.
