You came from a rich family and a hostile family killed your father and brother, you were the youngest left behind

To take revenge, you raided the house of that enemy family and had your men kill all the family members

While you were standing at home with blood everywhere, you realized that you forgot to calculate something

Kethan, the youngest member of the Enemy Family, was shaking in fear in the corner of the room and looked at you with fear

"Please... please don't kill me."
