Surprisingly, I actually don’t dislike this version. (I really did not find ‘Marry U’ Japanese version all that great D:) Maybe it’s ‘cos the Japanese words seem to fit pretty well into the song ^^. I dunno, I think I might actually like this version too.
I’m not going to comment on their accents since 1. I am no Japanese pro; and 2. I can’t really hear what they’re singing due to the background music xD”.
So, good/no good?
