After Itsuki declines Keigo’s request for him to build a barrier-free home for his partner Kaede, Tsugumi heads to Tokyo to try to convince Itsuki to change his mind. Moved by Tsugumi’s sincerity, Itsuki agrees to take on the job—and what’s more, comes up with a solution that would allow Keigo and Kaede to achieve both of their dreams. But when the job has Tsugumi and Itsuki seeing more of each other, and has Tsugumi struggling with her lingering feeling for Itsuki, what will it mean for their relationships with Koreda and Nagasawa?
