歌词：Rihanna. I know.

*I know* verse 1: Took a chance Rolled the dice on me and you Opened up...let you in my world Like a dance Started slow and then love took control Swept away...so proud to be your girl But when you write a story much too fast Sometimes a happy ending doesn't last Chorus: Now I know that love ain't meant to be a play thing Now I know it's not a ordinary everyday thing Now I know that when it's right it's so amazing But when it's wrong you gotta let it go Now I know...now I know... verse 2: Remember when... We said our love would last forever But then again how are we to know? There's comes a time... That love will change like stormy weather A sunny day can suddenly turn cold Time will teach you all you need to learn But there'll always be a first time you get burned Chrous 1x Ad lib: I don't regret a single day With joy and pain along the way A broken hearts the price we pay Sad as it may seem Baby can't you see It's the way it's gotta be... Chrous til end I know...
