When asked to form an idol unit for her next single, Sumire decides to ask Rin to become her partner, feeling that the new song fits Rin's dancing ability perfectly. As the pair train for their single's debut concert, Rin tries too hard to live up to Sumire's expectations and ends up spraining her ankle, resulting in Johnny forbidding her from further dance training until it heals up. Feeling guilty for dragging Sumire down, Rin suggests that she choose someone else to partner with. Not willing to give up on the unit, Sumire decides to perform the concert by herself and have Rin coach her on her dancing, carrying both of their spirits on stage, after which she announces Rin as her partner to shine alongside with.
