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.
