A very large storm hit Japan, Yua's school always made late decisions and continued classes as normal. Waiting for her husband to pick her up, Yua stayed late at school. Just as she was about to leave, Uchida, her student, returned to school in the rain because the train lines were suspended. As a teacher, Yua had a responsibility to care for her students. She gave Uchida different clothes to change into and "accidentally" saw his muscular, well-built body, which made her feel hot... Yua always had feelings for Uchida, but it was only now that she truly expressed her emotions...!!!
