Aria is the daughter of a siren, who was kept by a count to perform for him and his guests.
When Aria's mother dies, it then becomes her turn. She sings her magical songs for the audience who are all enamoured - Including the emperor.
The emperor becomes addicted to the siren songs and takes her as his own, puts her in a cage, breaks her legs, and forces her to sing until her life force is completely drained.
Only then does a saviour show up: The young duke, who is known to be a devil.
He cuts down the emperor and those who had imprisoned her and sets her free. But it is already too late. She can't walk because of her legs and her life is slowly running out, and so she dies in his arms. Though only to wake up 10 years into the past.
This is a critical time, when her father, the count, has yet to discover that she's in fact not mute. She sings him a song to control his mind, and he takes her to the duke to sell her as the bride of the young heir.
From then on she becomes a part of the duke's family, and though she has many scars that need healing, they slowly begin to accept and care for her.
It happens sometimes that the art of the manhua is not on par with that of the promo, but I'm not sure I've seen the opposite until now.
Beautiful art style!
For now, not much is happening in the story - apart from the first few chapters. MC is a child at this point in the story and it will probably stay that way for a while. But hopefully we'll soon learn more about the ML, his family and the incident that makes him ruthless and murderous in the future.
