They were never meant to be in love-just married. Sky is a calculated businessman, known for his silence and sharp edges. When a political alliance binds him to Nani-the bright, soft-spoken kindergarten teacher and youngest son of a powerful Thai-Chinese tycoon-it's a move to protect reputations, not hearts. But behind Nani's easy smile is a secret his family keeps buried: a rare heart condition slowly threatening his life. And behind Sky's emotionless exterior is a man who begins to care more than he should. In a house built on obligation and silence, two strangers navigate power, illness, and the quiet ache of growing too close. Some marriages start with love. Theirs starts with a contract. What grows in the silence might be something neither of them are ready for.

"Under the Sky's Protection" Nani Hirunkit, a skilled and sharp-tongued surgeon, had no idea saving a stranger would pull him into the dangerous orbit of Sky Wongravee-a powerful, enigmatic weapons dealer with a fierce reputation. Kidnapped and forced into Sky's world to be his exclusive doctor, Nani finds himself caught between chaos and chemistry. As danger closes in, Nani and Sky must navigate a deadly game of power, betrayal, and secrets, where loyalty is tested and hearts are on the line. Who's really protecting who?

As the only Omega heir of the Four Fang Alliance, Nani Hirunkit is untouchable-protected by power, intelligence, and the unwavering loyalty of his Alpha friends. He doesn't need a mate. He doesn't want one. But his mere existence draws the eyes of every Alpha who dares to claim him. Yet amidst the growing tension, one presence unsettles him the most-a wolf unlike any he has ever encountered. Powerful. Unyielding. Dangerous. Sky Wongravee. Their paths were never meant to cross, yet fate has other plans. Because for the first time, Nani's wolf recognizes a mate. And this time, running may not be an option.

Nani has the special ability to see red strings of fate...threads that connect when two people are meant to spend the rest of their lives together. One day, he looks down at his hand and sees that his string has finally connected to someone!! But when Nani finds the person on the other end, he realizes it's... a guy called Sky!!!
