Yuna eventually figures out that the one Rio likes is Akari Yamamoto. Rio begins to confide in Yuna about his feelings and eventually falls in love with her. During the cultural festival, Rio decides to confess to Yuna because 1) his friend, who also liked her, confessed and 2) he heard Yuna was going to confess to someone.
