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.
When they say "a hole 
opened up in my heart,"
"عندما يقولون "فُتِحت فجوة في قلبي
Wenn man sagt,
dass man ein Loch im Herz hat,
Cuando dicen
que sientes un vacío en el corazón,
Cuando dicen
que sientes un vacío en el corazón,
Alors c’est ça qu’on ressent
quand un trou béant
È così che ci si sente, quando si dice
Será que é essa a sensação de
se ter aberto um "buraco no peito",
Наверное, в таких случаях
и говорят «сердце разрывается»?
