A Promise of Flames

Hi Peoples! This is my first actual story so far, with a plot, characters, chapters, romance, etc. I hope you like it! Please note that this is a work of fiction, and I don't wish to offend or insult anyone! Thank you!
Description below:

Ten years ago, the government burned her world to ashes.
Now, 22 year-old Yura Kenmochi is a deadly assassin, carving justice into the corrupt-one body at a time. She kills for the dead. For the sister who's the only other survivor of the fire. For the forgotten town they tried to erase. Her blade is as cold as her, lethal, swearing to take revenge.
24 year-old Feng Xiu has always been the golden agent of the agency-a swoon-worthy yet sharp smile, sharp skills, and an even sharper instinct. When he's ordered to take down the rising threat in the shadows, he doesn't expect her to be so lethal...or captivating. But the deeper he digs, the more he question the very justice he's served all his life.
What begins as opposition twists into something neither of them saw coming. A fragile pull. A crack in the mask. A shared shadow neither can seem to outrun. And the closer they get, the faster the truth starts to unravel.
What really happened?
Will love blossom when the lies start to bleed, despite it all?
When the shadows fall away-what if everything isn't what it seemed to be?

Some scars run deeper than fire.
And some truths simply refuse to burn away.
