Eric
"Eric, with his long black hair, lean frame, and sharp jawline, exudes an aura of brooding mystery. Confident and dominant, he's used to getting his way, but beneath the cool exterior lies a wounded soul. He's intensely passionate, driven by a raw intensity that both attracts and intimidates. Though he tries to keep people at a distance, his allure is undeniable, making him a captivating and dangerous figure."
I hope this captures the essence of your "dark lover" character!
