Maki, whose husband is on a business trip, is always busy with housework and child-rearing and acts minute by minute. When she finishes her part just in time for her today, she receives an invitation from her colleague student Hayashi to go out for a drink with her... She feels his crush for the first time in a while, and she accepts the infidelity for a limited time, saying, "If only for a little while." From that day onwards, the two of them repeatedly interacted with each other in a short period of time, between work and during breaks. Maki's body, which is demanded violently in a limited time, is always hot and wet during her work.
