Seina Yamada has been waiting so long to return to his home, Earth.
But so much has changed; his sister is engaged to Kiriko's brother Kai,
and his parents' old store is now a huge mall.
Furthermore, he is to stay at Kiriko's mother's house...
It looks like my growth spurt came late.
يبدو أنّ فورة النموّ خاصّتي تأخّرت
Mein Wachstumsschub
hat etwas verspätet eingesetzt.
Crecí de golpe un poco tarde.
Di el estirón un poco tarde.
J’ai grandi un peu sur le tard,
en fait.
A quanto pare il mio picco di crescita 
è arrivato in ritardo.
Parece que eu demorei
um pouco para crescer.
Похоже, мой скачок роста чуть запоздал.
