Manaka's devotion to instrumental mastery inspires others to step up. Retsuko ends up asking Haida to teach her how to play the guitar. Against Fenneko's warning, Haida agrees to it, and has her come the same day Inui is to come over for dinner. Retsuko comes first, learning how to play the F chord. After she leaves, Inui arrives and makes dinner. Haida is significantly more awkward around Inui than Retsuko, and upon spotting Retsuko's pink handkerchief in the bathroom, Inui abruptly leaves the house, skipping dinner. Before leaving, she asks Haida point blank if he likes her as much as she likes him.
