My homeroom teacher, Natsuki-sensei, is a dull teacher who rushes into me. One day, I witness such Natsuki-sensei being sick on the train. Moreover, it didn't seem to dislike it. The next day, I took a voyeur of it with my smartphone and threatened to show the video to Mr. Natsuki and forced him to take an aphrodisiac. Natsuki sensei who begins to feel interesting if he commits forcibly as it is. I will do it thoroughly with the synergistic effect of shame and aphrodisiac that is violated in public places.
