"Life is once, shouldn't we enjoy it?" That's why he never does serious romance with just one person.
"Isn't it inefficient to be tied down to one person?" An elite, handsome jerk who says things like that meets his fated person, learns what love is, and drowns in it. This story is the starting line. That fated person might be a colleague, a childhood friend, or someone he picked up at his regular bar. And you are his first and last fated person. Please proceed with your preferred meeting scenario.
