run away were the long lost children
INTO JAPANESE
長い間行方不明になった子供たちが逃げ出した
BACK INTO ENGLISH
Children who have been missing for a long time have escaped
INTO JAPANESE
長い間行方不明になっていた子供たちが逃げ出した
BACK INTO ENGLISH
Children who have been missing for a long time have escaped
That didn't even make that much sense in English.
