The protagonist is university student and works part-time at a family restaurant. Miori is a married woman with extremely timid personality and lacking confidence in herself. Due to her husband's salary cut at work, Miori has to work part-time at the same place as the protagonist's. Because she has always been fulltime housewife until now, she has zero experience in working and makes a lot of mistakes. As the time goes on while Miori gets help and supports from the protagonist, the two gradually become closer as part-time fellow workers. However, they never expected a small happening would change their relationship forever.
