Yasu, the drummer for Black Stones, informs guitarist Nobu that Ren has been invited to join Trapnest, a group of friends debuting on a major label. Facing uncertainty about the band's future, Yasu decides to leave Black Stones to resume his internship as a lawyer. Simultaneously, Nana O. resolves to end her romantic relationship with Ren, aiming to achieve success based on her own merits rather than her connection to him. Following these developments, the members of Black Stones disband and gather at the train station to bid farewell to Ren as he departs.
