I kind of know what this means, but damned if I can think of a way to translate it with any sense of poetry. It's kind of like 'The person that resides always in my heart, when she is in my arms, I must realize that she is my rival in love.'

Kind of like that. Someone else with some decent writing skill, play with that.

I don't know about writing skill, but I hope people like this translation.

Oh god yes.
