During their first live performance, Akihiro played on his own again and Souta became infuriated and they fought. Yui then confronted them backstage and reprimanded them.
Souta suggested undergoing a training camp and he agreed. Souta accused Akihiro of not being able to follow a rhythm but Akihiro insisted that he could but chose not to.
