how do you say my emperor love
iam trying to say he is the king of my love
You can say:
"Eres mi rey" (you are my king)
He is the king of my love
I don't find an equivalent to that in Spanish. The only sentence I know is "él es el dueño de mi amor". I mean, he has some influence or power on me through love.
Marianne is correct.
Eres Mi Rey
