It's the day of the school's ball sports tournament. Izumi-kun is playing soccer with the boys, and Shikimori-san is participating in the girls' volleyball match. Izumi-kun knows he can't contribute much, but he plays his hardest anyway. Shikimori-san worries about him, given his natural unluckiness... and surely enough, he gets hit in the face by a soccer ball and blacks out. He ends up in the nurse's office while Shikimori-san looks after him, meaning the two of them are alone. Then Shikimori-san says she's going to stay with him instead of heading back to play in the volleyball match...
You know you're the only one 
I want to walk home with.
تعلم بأنّك الشخص الوحيد الّذي أريد
أن أمشي إلى المنزل معه
Dass du nicht der einzige bist,
der gemeinsam nach Hause gehen will,
Tú sabes muy bien que eres el único
con el que quiero caminar a casa.
Sabes perfectamente que eres el único
con el que quiero volver a casa.
Tu sais très bien
Sai bene
Você sabe que é o único com
quem eu quero ir embora.
Сам ведь знаешь, ты единственный…
