You will regret ruining my heart deeply, for there is no other guest residing in this house except you.

The poet imagines their heart as a welcoming home where the beloved is the only cherished guest. With a tender yet haunting warning, they remind the beloved that in devastating this heart, they are destroying their very own sanctuary. It captures a profound truth of love: when you ruin the space someone built for you, you ultimately leave yourself with nowhere to stay.
