I am unable to decide whether this heart is mine or it belongs to you.

This couplet captures that beautiful, dizzying stage of love where the boundaries between 'you' and 'me' simply melt away. Physically, the heart beats inside the lover's chest, yet its desires, whims, and pain belong entirely to the beloved. It is not a complaint of confusion, but a tender confession of complete surrender where claiming ownership over oneself no longer matters.
