Yuriko is a female teacher who has been transferred to a famous high school. Yuriko was given the responsibility of providing guidance on daily life, but as it is a high school, all the students are serious and excellent. The only thing I'm worried about is that I don't have energy and it's closed... One day, Yuriko was secretly photographed inside her skirt during class, and she called out to ask the student about the situation. However, Yuriko, who is worried about the future due to her students' shy attitude, decides to provide adult lifestyle guidance by the first semester and the second semester, which will soon be over.
