Kakeru enters the soccer club as a provisional member, just as the letter says. When the topic of lunches comes up after practice, Kakeru jokingly asks Naho to make lunch for him as well. Naho finds herself bewildered by his words, but feels pushed to act by the letter from herself 10 years in the future, which tells Naho that she wishes she had made lunch for Kakeru.
And if you can't get up in the morning, 
I'll give you a wake-up call!
،وإن كنت لا تستطيع الاستيقاظ في الصباح
Und wenn du morgens nicht aufstehst,
dann rufe ich dich an und wecke dich auf!
y te llamaré por las mañanas
si no puedes despertarte.
y te llamaré por las mañanas
si no puedes despertarte.
Et si tu n’arrives pas à te lever, 
je t’appellerai pour te réveiller !
E se hai difficoltà a svegliarti la mattina,
allora ti chiamerò per svegliarti!
E se você não conseguir acordar cedo,
И если не сможешь утром проснуться,
 я разбужу тебя звонком!
