It is soon apparent that Aoi harbours feelings for both the Aiba brothers. However, building on her relationships with the boys was impeded by her lack of will to deal with her feelings. By the time Aoi realized what her feelings were (apparently, she prefers Kouji), Kouji was pursuing a relationship with his own crush, Fina S. Shinozaki, and Yuki's attitude made it impossible for any save the most foolish or most persistent to get close to him. By the end of the series, all relationships and emotions are resolved, and Kouji and Aoi return to the Ryvius as an official couple.
