A few years back, Homare, Izumi, Jun, and Kanata lived together in a share house while working as an idol group, but they were unexpectedly fired. While in a slump, they found and helped Gakuto who had apparently collapsed from hunger and was lying on the side of the road. The four were moved by Gakuto, who came to Tokyo to make music, and his singing. Later on, Izumi is invited by Homare and the others to join a band. But try as he may, he worries about the future, unable to take the first step forward...

Confusion hits everyone at sMiLea Production when an article in a weekly magazine states that the person who forced Lin to retire from being an idol was Daiki. The group's lead still has yet to be decided, and there are rumors that the joint live performance will be canceled. But while everyone gets increasingly anxious, only Akira continues to believe in Daiki. Akira does his best to support LEGIT's work and make the joint live performance a reality with persistence and a positive attitude. One day, Akira runs into Daiki at the same school he attends for supplementary lessons...!
