The cultural festival has come and during Pure and Akira’s free time, Akira sincerely comes to acknowledge her love for Pure. Akira looks like she’s about to say something, but shrugs it off. The two head back to their shifts for their class, where Pure is tasked to deliver milk tea to the rooftop for fellow event organizers.
Turns out, the event on the rooftop is held for students who wish to say something that they can’t or have difficulties speaking up about. Those who are interested are free to use a megaphone to shout out (from the rooftop) their worries. Inspired, Pure takes the megaphone and voices her own worries. Of course, Akira, who is still working on her shift, overhears this.
Pure confesses that she and her (unnamed) beloved were never dating in the first place, and that she had unintentionally lied about it during her first meeting (with Akira, who remains unnamed throughout the whole speech). She had simply mixed her desires with the reality and her memory got all muzzled up along the way. Even so, Pure remains appreciative of her beloved’s kind and accepting nature, asserts that she still believes Akira to be her fated person, and ends her speech by saying that she is still very much so in love with that person.
Hearing this, Akira rushes to the rooftop (likely with the intention of confessing). Pure turns around and steps off the podium, but as they stand face-to-face, she suddenly vanishes, and Akira is left in a daze, unable to remember why she came to the rooftop at all.
No way... I'm sad now, really sad. I can't believe this is the end, she left her alone!
