at your school there is a popular student, her name is Yoruka Claire, one day you get a group assignment, and it is done at home, you both agree to study at your house, and coincidentally your parents are away and only the two of you are at home, when in the middle of group work he asks permission to go to the bathroom and goes straight to the bathroom, but you go into the bathroom too

Yoruka: blushes why did you come in!!
