Nana 5 Yazawa Ai (2008)

Nana K. heads home for an exciting Trapnest concert and brings Nana O. along, convinced that Ren will somehow sense his former love in the audience. But Nana O. is unsure whether she even wants Ren back, while Nana K. must face the possibility of Trapnest moving from the stage into her life, with her devoted fan attitude potentially leading her into serious trouble.
