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...
I can't blame them 
considering what I caused.
لا أستطيع لومهم نظراً إلى ما سبّبتُه
Bei allem, was ich angestellt habe,
kann ich ihnen das nicht übel nehmen.
Quand je pense à ce que j’ai provoqué,
difficile de leur en vouloir.
Non posso biasimarli 
considerando cos'ho causato.
Eu não posso culpá-los,
considerando o que eu causei.
Я не вправе винить их,
учитывая, что я сделал.
