His Reluctant Bride by RT Singh

Advika Pradhan spent her life in the shadows—her father’s shameful secret, invisible to everyone who mattered. When he forces her into marriage with his greatest enemy to secure peace, she expects a prison. What she gets is far more dangerous: a husband who looks at her like she’s a problem to solve, a family that treats her like the enemy, and a desire that burns hotter than hate.

Sidharth Singhania doesn’t do love. Betrayal killed his parents and hardened his heart. His new wife is a Pradhan—the daughter of his rival, a beautiful trap he can’t afford to trust. He’ll keep her at arm’s length, use her for the alliance, and never let her close enough to destroy him.
But desire has a way of shattering the best-laid plans.
She’s the poison he was forced to swallow. He’s the addiction she can’t survive without.

He comes to her bed at night but won’t stay till morning. She falls in love with a man who can’t say the words back. And when jealousy, suspicion, and buried trauma collide, they’ll have to decide: is this marriage worth fighting for, or should they let it burn?
