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...
Maybe I am overthinking it?
ربّما أبالغ في التّفكير في الأمر؟
Denk ich zu viel darüber nach?
Forse mi sto facendo troppi problemi?
Será que eu estou preocupado demais?
Может, зря я так волнуюсь?
