Why is Sensei here?

　　Even on summer vacation, Mafuyu still dedicates her life to education.

　　Currently she is one of the cram school staff. Because her qualifications are not sufficient to become a professional lecturer, she helps with the logistics of processing materials that other lecturers need to use, as well as looking for opportunities to attend lecturer lectures to improve her own teaching skills.

　　Summer vacation was a time for students to relax, but for a mature and wise adult like her, it was a journey from one stage of study to another.

　　Of course, that had nothing to do with her doing nothing but work and study!

　　...Only children could deceive themselves and others, but Mafuyu was already an adult.

　　Yes, she's a boring girl.

　　Doesn't have a boyfriend, and has no interest in going out to play. Besides, all friends know her temperament and rarely ask her out. Only one friend who is also a teacher in Chiba City always wants to take her out for a trip.

　　However, the other party was an alcoholic, and Mafuyu knew that she couldn't drink well, so she avoided alcohol.

　　So this past vacation, she spent day after day at her home, school, library, convenience store, ramen restaurant and other places, with little entertainment, almost completely out of touch with today's youth.

　　Mafuyu understood her flaws.

　　Despite appearing cold and aloof to outsiders, she just does what she wants to do.

　　If she is not interested, she will not contact and spend time in a proper and efficient manner.

　　Mafuyu never complained about it.

　　This is the men's room on the second floor of the cram school, no doubt, it is the men's room on the second floor.

　　So what...

　　"Why, Sensei is here?"

　　 Shinichi looked at Mafuyu who was sitting on the toilet half naked.

　　Since there were no classes in the comprehensive class this afternoon, Shinichi greeted Fumino and Kei on the stairs at noon, then they were about to leave school and go home to take a nap.

　　On the way, he suddenly remembered that something was left behind at school, and after he ran back to get it, his bladder was vibrating again, so he went to the toilet.

　　About fifteen minutes into class, all the classroom doors were locked, the corridors were empty and very quiet.

　　Shinichi passed every classroom.

　　Just like that, he walked lightly towards the toilet, and found that from the side door of the stairs, there were traces of water spreading into the men's room.

　　Shinichi looked at the women's restroom with a cleaning warning sign outside the door, and was about to enter the "Sherlock Holmes" state to think, but the pain in his stomach swept over like a wave.

　　Shinichi didn't have time to think, so he ran to the men's room and was about to rush inside to free himself.

　　Then, he met Mafuyu who was drenched in sweat and undressed.

　　Then, why did Mafuyu take off her clothes in the men's toilet?

　　The awkward silence lasted for a few seconds.

　　Shinichi slowly came out of the toilet cubicle, closed the door, leaned against the door panel.

　　He clamped his legs tightly, and his whole body trembled slightly.

　　Shinichi really wanted to go to another toilet.

　　This toilet wasn't the only one left, and he didn't have to endure the pressing pains of living here.

　　However, let the revered female teacher hear his voice and smell the 3-methylindole, such a shameless thing should never appear in his life.

　　Either it doesn't happen, or it dies, there is no other possibility.

　　Shinichi only has two choices.

　　Currently, he had been cornered.

　　One of them was to immediately take Mafuyu out, even if just for a moment, it was enough for him to carry out a gradual release.

　　The second was him defecating on the spot, and finally killed himself in anger, ending this shameful life.

　　When dignity equals life, there is no need to consider which one to choose.

　　So now, he would risk his entire life for that very moment!

　　 Shinichi took a deep breath and spoke.

　　"With Kirisu Sensei's character, it must be by accident that she came into the men's toilet to change."

　　Even though his stomach hurt, he was still able to think rationally.

　　It's impossible to come here just to feel the excitement, right?

　　Shinichi heard Mafuyu's cold voice holding back her embarrassment.

　　"Makes sense. It's a huge help that you can react so quickly, in fact…"

　　After that, Mafuyu told the whole reason.

　　In short, ten minutes ago, in order to save a bird that was accidentally injured, she accidentally fell into the fountain behind the school. There was no one to help, so she could only take advantage of the rare class time, go to the toilet to hide and think of a solution.

　　However, there was an uncle who was cleaning the women's toilet, so she could only hide in the men's toilet in the hope that everyone was in class and no one would come now, and wanted to take off his wet clothes first, otherwise it would be inconvenient to do so.

　　Unexpectedly, someone suddenly opened the door and barged in at this time.

　　Obviously she had noticed the footsteps...

　　"I see..."

　　Shinichi didn't know what to say.

　　This kind of development was too fortuitous, so he really didn't want to complain.

　　Not only that, but he also had something to say to Mafuyu, who was sighing depressed inside the door.

　　(Can't you lock the door?)
