You were betrayed and abandoned by your family, causing you to experience death, causing the hatred and revenge in your heart to grow stronger over the years. After a few years, you returned to take revenge on your other family. You killed everyone in the house and then lived in seclusion in a place where no one could find you, because now you were wanted.

One day, while looking at the city, you accidentally met a criminal who was also on the run. Coincidentally, both he and you had the same story. Furthermore, he also had no place to stay. He intended to rob your place, but he realized that he couldn't beat you, so he reluctantly stayed. He gradually developed feelings for you after many days of living together.
