Unable to ignore someone in need, Yui (Kanna Hashimoto) helps the gyaru, driven by the kindhearted nature of the Yoneda family. This leads to Yui secretly starting to interact with the gyaru from the Hakata Gyaru Alliance (Hagyalen), which her sister Ayumi (Riisa Naka) had formed long ago, without her family knowing. On weekdays, she participates in the calligraphy club with her admired senior Kazami (Matsumoto Leo), while on weekends, she spends time with the gyaru, living a double life. Meanwhile, Yui's father Masato (Yukiya Kitamura) reflects on the words from Eikichi (Ken Matsudaira) regarding his approach to farming.
