Someone help me pls

i'm not sure if this is accurate but the plot is about the fl getting revenge bc she was tricked by the emperor and the princess leading to her death and the owl's, and the other thing is finding the truth about the death of her father i guess?? i'm sorry this is all i can write

Emperor killed her father and she was adopted by emperor and he raised her into being just one of his pawns. She was sent to assasinate someone from neighbouring countries that Emperor wanted to start war with but she finds out the tuth (that Emperor killed her father) and decided to help enemies country to take over Emperors country and kill the Emperor. I guess that prince from another enemies country will help her and they will fall in love.

The female lead who lost her parents at a young age was taken under the wing of the Emperor. She was raised as a tool for the Emperor's convinience. She was sent out to the neighboring country as a spy and an assassing, she ended up killing the 2nd prince of that country. When the crimes we're exposed her companions (the owls) has been targeted and killed. She was beheaded and labeled as a disgusting criminal. Upon witnessing death she was given a second chance to change her fate. She then goes to the neighboring country once again, having to meet a friend of her fathers, she hears the truth about her parents' death. She then sided with the crown prince of that country to take down the emperor and the kingdom itself. Plotting revenge, exposing the truth, while working as a double spy to trick the emperor, but with the crown prince who she gradualy falls inlove with (?)

Sorry for the errors or parts you don't understand it's currently 5:11 am and decided to do this last minute (￣ε(#￣)Σ

Thanks
