Ep. 21: Junichi volunteers for the Founder's Festival committee and discovers Tsukasa's hidden side.
A year after being stood up, Junichi skips the Founder's festival until Masayoshi invites him over. Deciding to change, Junichi surprises everyone by volunteering as Tsukasa's assistant for the committee. He admires her work ethic while trapped in a storage room with her, but Miya and Sae interrupt their time together. On the way home, Junichi encounters Tsukasa's older sister Yukari, causing Tsukasa to act displeased and drag her sister away. The following day, Tsukasa substitutes for Kaoru and Keiko in swimming classes yet still assists Junichi with festival issues. Later, Junichi finds a notebook in the classroom and attempts to identify the owner. Tsukasa arrives in her swimsuit, demanding to know if he read it, before suddenly dragging him by his necktie and revealing a different personality.
