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...
Remember how we all used to 
sleep in the same room like this?
أتتذكّر كيف كنّا جميعاً ننام
في نفس الغرفة هكذا؟
Früher haben wir doch immer
alle zusammen geschlafen.
On dormait souvent ensemble,
avant.
Ricordi che dormivamo
tutti nella stessa stanza?
Lembra como dormíamos
todos no mesmo quarto?
Раньше мы часто спали в одной комнате.
