Like the rest of the world, Japan finds itself displaced by the pandemic. Thus, causing many universities, as well as institutions to close. This leaves current students with no other alternative than to study remotely, and at home. Kei Nakamura is such a student. In order for her to continue her studies, a tutor in Tony, has been brought in to assist her. For Kei, it is a normal day of studying, as she thumbs through a book, in an effort to solve a problem, as Tony is by her side with a watchful eye. Things are going well for Kei. That is, until she arrives at a part of the problem that she just don't understand. Tony does his best to help her solve it, and it is initially that she believes that she has got it. But, unfortunately, soon finds herself stumped once again. Her displeasure in being unsuccessful, leaves the college student very frustrated. Tony, the tutor taking note, then decides to give her more than a little helping hand, in an effort to calm her nerves. This, as he begins to touch her in a sexual manner. It's a compromising position. One that nearly gets them caught by Kei's Mom, when the two happen to hear a knock at the door.
