During a retreat, she receives a confession from one of her male seniors, but being oblivious, she brushes it off by saying he is a good senior. Things then become awkward between them. Feeling sorry for the situation, she asks her senior if he desires her. Initially intending just to kiss, the two end up progressing into sex. However, at that moment, another male senior approaches the place where they are.
