It has been 5 years since I joined a stationery manufacturer as a new graduate. - Due to the recent social situation, business has deteriorated, there are rumors of a company acquisition...and then a proposal from her boyfriend. - Mahiro, a single-parent family, is torn between wanting to get married soon and give her mother peace of mind, and her own feelings of not being able to get married. - Meanwhile, Atsushi, a colleague of mine, came home from work during overtime. - The two had a drink for the first time in a while while talking about their memories from when they first joined the company.
