YOU SAID:
Ugliest person is the person on the opposite side of the mirror (YOUR BROTHER)
INTO JAPANESE
最も醜い人は鏡の反対側にいる人です(あなたの兄弟)
BACK INTO ENGLISH
The ugliest person is the one on the other side of the mirror (your brother)
INTO JAPANESE
一番醜い人は鏡の向こうにいる人(あなたの弟)
BACK INTO ENGLISH
The ugliest person is the one on the other side of the mirror (your brother)
That didn't even make that much sense in English.
