The General's Blind Bride

She was sent to betray him.
Blind since she was eight, scarred, and unwanted, Shen Qingyin has spent ten years waiting for her father to find a use for her, and he finally does. An arranged marriage to Lu Chengyuan, the empire's most feared general, a man in disgrace with secrets worth killing for. Her orders are simple. Marry him. Watch him. Report everything.
So she reports everything. What he eats for breakfast. The weather. The dog.
Chengyuan buried his parents and one wife already and learned the lesson the dead teach best. Everyone close to him dies. He wants nothing from the bride planted in his house. But she maps his estate by sound and counts his footsteps and reads the killing intent of men his own soldiers can't see coming. And when the whole world calls her damaged goods, he finds himself standing very still, deciding who dies first.
She knows closeness is a leash. He knows love is a grave. Neither of them knows that their past bound them together, and that everything between them, the marriage, the treachery, the war coming from the east, grew from that single moment.
A slow-burn arranged marriage wuxia romance featuring a blind heroine who is never cured, a general with the emotional accessibility of a locked armory, one useless spy report at a time, and a love that survives the truth.
Open door in the back half. Guaranteed happily ever after. No cliffhanger, no sequel bait, no miracle cure.
For readers of C-drama slow burns, morally gray courts, and men who communicate exclusively by rearranging household security.
