YOU SAID:
never gunna give you up never gunna let you down never gunna turn around and desert you!
INTO JAPANESE
ガンナは絶対にあきらめず、ガンナは絶対にガンナを落とさず、ガンナは絶対に振り向いてあなたを捨てない!
BACK INTO ENGLISH
Gunna will never give up, Gunna will never drop Gunna, and Gunna will never turn around and abandon you!
INTO JAPANESE
グンナは絶対に諦めない、グンナは決してグンナを落とさない、そしてグンナは決して振り向いてあなたを見捨てない!
BACK INTO ENGLISH
Gunna will never give up, Gunna will never drop Gunna, and Gunna will never turn around and abandon you!
That didn't even make that much sense in English.
