With the sports festival now in full swing, the performance of the cheerleading squad is a great success, and Ishigami is overcome with a sense of fulfillment that he has never experienced before. However, when a classmate from middle school, Kyoko Otomo, approaches Ishigami, his facial expression completely changes. While still being visibly rattled, he is chosen to replace the injured leader of the cheerleading squad as the anchor for the relay race. As a pale faced Ishigami steps up to the track, he begins to reflect on an incident he once caused in the past at school...
Fifteen years old,
and you can't even say you're sorry?
أنت بعمر 15 سنة
ولا تستطيع قول كلمة اعتذار؟
Du bist jetzt 15 und bringst nicht einmal
ein „Entschuldigung“ heraus?
Ya tienes quince años, ¿y ni siquiera
 puedes decir que lo sientes?
¿Tienes 15 años 
y ni siquiera puedes disculparte?
Tu as 15 ans,
mais tu ne sais toujours pas t’excuser ?
Já tem 15 anos e não
consegue nem se desculpar?
Пятнадцать лет парню, а он даже 
«извините» написать не может!
