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...
but my parents are 
in the detached house.
لكن والدَي في البيت المنفصل
ma nella dépendance ci vivono i miei.
Mas meus pais estão numa casa separada.
