55-year-old Uekusa Chiaki (Taguchi Tomorow) creates architectural models and has gained a following on social media for his interest in nostalgic and cute “girly architecture”. 26-year-old Haruno Fuji (Ikeda Eliza) works for an advertising agency and dreams of opening her own cafe with her friend Ayako. She has been following Uekusa’s account for ideas. They get acquainted through social media and gradually connect with each other as they tour architectural masterpieces. Fuji has a lot to worry about in work and in love. But she is moved and emboldened by Uekusa’s offhand comments coming from his peculiar set of values and unique perspective, to move forward.
