Tomoyo recalls how she first met Jurai during her chunibyo days. Meanwhile, Hatoko tries to follow a magazine's advice to get Jurai to fall for her during their vacation, though not too much success. Upon his return, Jurai invites Tomoyo to a summer festival where they talk things out and watch the fireworks together, leading Tomoyo to realise she is also in love with Jurai.
