The poor 60 minutes of the video is the happy time advertisement of the bad boy when he "slapped" his tutor.
Teacher Iori has just graduated from school and wants to earn more income, so she has accepted tutoring at her home for families with conditions, wanting her children to study better. That evening as usual, Iori was on her way to the house of a high school student to teach part-time, because she thought the place was close, so the girl didn't bring an umbrella, unfortunately it was raining, Iori got wet in many places when she arrived.
The tutor was taking a shower and changing clothes when she didn't expect the student to rush in to take a bath together, at that time there was no one in the house, knowing that she might be in danger if she resisted, Iori "gave up" and accepted to take a bath with the naughty boy.
