Transmigration: From Assassin To Capable Husband

Ariel Atoms was born to a loving family. However, due to circumstances, she was forced to be in an underworld organisation; working as a top-class assassin.
Over the past 20 years, she has killed millions of innocent and guilty people; good and bad; male and female. Her hands — no matter how many times she washed them — are still stained with blood of those she killed. Only death surrounds her and they identify her as “Cold Blood”.
She was the most wanted criminal throughout the world and yet, her heart felt empty. She was not living. She was not happy. She was merely following orders from the higher-ups.
If she could, she would restart her life. She never wanted to be a murderer. She wanted to live happily and have a family of her own; a home to go back to.
The day came when she decided to stop killing. She got tired. The only way out was to kill herself.
She was never afraid of death. She killed herself where no one would ever find her corpse.
When she came to, she woke up as another person; a weak young man. This person was not weak physically but mentally. He was abused mentally and she just happened to possess this man’s body.
She was no longer Ariel Atoms, the top-class assassin everyone feared.
He was now Ajax Rodney, the weak rodent whom everyone bullied and made fun of.
That was about to change and this was his story.
