I think it's carnal sins as well. Sounds very familiar.

But I wanted only keep my love
Every cardinal sins
Every immoral things
But I was holding on for my love

That's how I hear it...Just like nmskalmn posted it. But i have to say that we're going in circle's :P Ayu should stop messing around with us and post real lyrics :D lol

Well she can't pronounce those words very accurately...otherwise it wouldn't fit into the song. Could go either way then. When I hear it, she says "sins" like "sis"...and I almost hear the word "promises".

OMG... Ayu is indeed really special.. It's my 1st time to hear the word "cardinal sins" in a song and only ayu did that...That's amazing...

It's not "every cardinal sin".

It sounds more like "every carnal sin". I can't understand the rest. I know some here will say "it's cardinal", but deal with it, she is more surely talking about sexual sin here.

Lyrics are not written in the booklet probably because there were a lot of lives of this song and japanese have the legal obligation to write english lyrics on screen. Ayu maybe didn't want all the nation to see "every carnal sin" on screen.
