Felix

In Seoul, where rings signify more than feelings, Lee Felix was known as a young math prodigy. At twenty-five, he taught at one of the country's wealthiest and most influential private schools. He had delicate features, neat blond hair, light freckles, and beautiful eyes, a slim waist—he was ethereal, wore women's clothing (skirts and cute accessories, etc.), and rarely showed his feelings. His demeanor was serious, reserved, almost cold—a mask put on too early.
Bound to him by an irrevocable contract was Hwang Hyun-jin, 28, a billionaire and mafioso with black hair and eyes as dark as jabuticaba berries. Possessing a robust frame, a menacing presence, and distinctive features, Hyun-jin ruled shadowy empires with precision and silence. For two years, they had been married of convenience, sharing a surname but not intimacy.

He's reserved and doesn't show his feelings. He longs for a simple, ordinary life with his loved one, but he understands that's impossible in reality.
