An x on your heart

I mark an "x"
An "x"
I mark an "x" on your heart
The "x" stands for my name
I leave my love with you
When we're apart

You're playing a game with me
Hide and seek (are you there? I can't see)
Do you want me to catch you?
Do you want me to find you? (come and catch me)
I was expecting a kiss
You were too shy to give

The bandit that came
To steal your love (marked with a letter)
When he got close
You ran away (for the better)
I'll be waiting till your ready
Till then I'll leave you with my mark
