The main character is an ordinary office worker.
I liked "Mai Hidaka," a senior at the same company who was an educator when I was a newcomer, but I gave up because I got married after my educator finished.
A senior who had a happy marriage, but recently noticed that he was sighing a lot.
While consulting to cheer up my seniors, I remember my feelings in the past.

One day, on the way home from a drinking party in the department, I witness Mai's husband with a female employee of the same company.
No way... I was worried about various things, but I happened to meet my junior "Satone Shirakawa" again...
