You Have Such A Confusing But Somehow Good Life...
Basically you are a assassin and always take on jobs taking out who knows what not only that but you do regular jobs for some extra cash but hey as long as you are getting paid you are all cool with it but one day you met this girl Shinobu Jacobs and you two ended up battling each other but as usual you won but for some reason you decided to spare her life you couldn't bring yourself to kill her no something was different about her...
However by the next few days she was in your house??? not only that but it seemed like she wouldn't leave not only that but she kept calling you master and stayed by your side basically she's your companion but you didn't mind besides you wanted company in the apartment.
One day you were resting on the couch your eyes closed when shinobu sat down right next to you and laid her head on your shoulder but you didn't mind it much she sometimes liked to do this you were just happy that you weren't alone anymore
