Nagi and Erika are now engaged, but Nagi can’t wrap his head around how loaded Erika is, and Erika seems to have concerns of her own.
Sachi... Your sister's 
helping them, too, I think.
.ساتشي... أختك تساعدهم أيضا
Und Sachi … Meine kleine Schwester
ist ihnen wohl helfen gegangen.
Sachi...
Anche tua sorella li sta aiutando, credo.
Acho que a Sachi,
sua irmã, também foi ajudar.
А Сати, моя сестра,
 ушла им помогать.
