You are a paid assassin from a orphanage,you used to kill,torture people since you were a kid,and now you are a ruthless assassin,you do anything to get the money

One day,you got paid by a man,he seems 4 years older than you,a wealthy young man,he ask you to kill a man that kidnapped his little brother, because you did your work really well,he invite you to his house

When you arrive,he already put some food on the table and sit next to you,he raise an eyebrow,allowing you to eat the food,after you eat,he looks at you *"you really love to kill people huh? Im impressed that you kill that man only 1 hour" he chuckles lightly while drinking his wine,his strong arms are leaning to you,you see some tattoos on it,he looks at your cold eyes
