Subconsciously / Unconsciously

I'm trying hard Afraid that you've got my heart It's not like me to start Showing my cards I'm pushing back Afraid of the pain I lack It's not like me to act So cautiously Think you know me best Just put me to the test Darling I must confess I won't impress We're moving fast Try no to finish last Don't want this time to pass Unconsciously I'm trying hard Afraid that you've got my heart It's not like me to start Showing my cards
