Lyrics:

Are you sincere when you say I love you?
Are you sincere when you say you'll be true?
And are you really mine, every day, all the time?

I'd like know which way to go
Will our love grow, are you sincere?

Are you sincere every time that you kiss me
Are you sincere when you say that you miss me?
Can I believe every word that this is ever?

I'd like know which way to go
Will our love grow, are you sincere?

And are you really mine, every day, all the time?
I'd like know which way to go
Will our love grow, are you sincere?

Are you sincere?
