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...

back to some trouble.

Seina-dono avrà una spiacevole sorpresa 
al suo ritorno.
O Seina vai voltar bem
a tempo dos problemas.

в лапы неприятностей.
