Saito was found to be an incompetent employee just a few months after joining the company and was subjected to high-pressure, aggressive language by his senior colleague, Riko, which left him feeling very down. Amidst this, he discovered something called 'friend delivery health' where an acquaintance comes as a delivery health worker, and out of half interest, he called for one, only to find it was Riko. Though surprised, after enjoying the play with her, when he saw her at the company the next day, she had no memory of the delivery health incident. 'This is great,' he thought, and continued to call Riko as a delivery health worker multiple times to vent his daily stress.
