Ai Yori Aoshi

Synopsis

The photo club puts on a show with Tina and Taeko wearing outfits to draw attention. To this event comes Mayu, a girl who has been living in England and has returned to go to this college at 16. Seeing Kaoru, her mood improves and she flings herself at him and kisses him on the lips. Tina and Taeko are stunned by this. Mayu, who comes from a wealthy family, convinces Kaoru to come to her house for dinner. Kaoru informs Aoi of this though he neglects to tell Aoi that his friend is a female. Then Mayu convinces Kaoru to spend the night at her house since she's there alone. Again, Kaoru calls but doesn't let Aoi know that his friend is female. However, when Taeko lets it slip that she was surprised Kaoru's friend would kiss him like that and that the friend was female, Aoi is suddenly worried by this revelation.
