Maki, whose husband is on a business trip, is always busy with housework and child-rearing and acts minute by minute. When I finished my part on time today, I received an invitation from my colleague student Hayashi to go out for a drink. Feeling a crush on him for the first time in a long time, she accepts his unfaithfulness for a limited time, saying, "If it's just a little bit." 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 work.
