And like that you own my heart

In a heartbeat you've claimed my heart, It has become part of me thinking of you after I wake. It has become a part of me asking myself; What do you think his day feels like? Oh! and it has become a part of me mentioning your name in my prayers, even though I know not what I ask for And just like that you own my heart, You live there like you own it, Like it is yours to begin with.
