Everyone at Ryokushou is participating in the Miyama school district's sports festival. Itsuka feels shy and awkward around Nagomu, causing her to adopt a brusque manner toward him. But in his loud cheers of encouragement she feels the warmth of family. Nagomu's father, Heigo, gets overly fired up and ends up hurting himself. Nagomu and Itsuka have to step up to take his and Nagomu's place in the parent-child event. Meanwhile, at Ryokushou, a woman calling herself Itsuka's mother appears.
And since this is all so sudden, 
we haven't told her we're doing this.
وبما أنّ الأمر حدث فجأة، لم نخبرها
بأنّنا نفعل هذا
Aber weil es so plötzlich ist,
habe ich ihr nichts zu dem Treffen gesagt.
Y como fue tan repentino,
todavía no le hemos dicho nada.
Y como ha sido tan repentino,
todavía no le hemos dicho nada.
Visto che è stato tutto così improvviso,
non le ho detto di oggi.
E como isso tudo foi repentino demais,
a gente ainda não contou pra ela.
Всё случилось так неожиданно —
мы ей ничего не сообщили.
