Warning: there's a serial killer and it gets gross at one point

I was born in a poor family. I lived my sister and my grandma, my parents lived in another country because of their work. I've been saving money all my life so i could commission a tailor to make me a traditional high-class two piece cowl so i could go into the richer part of the city to marry someone and move my family away from the slums. My grandma had one herself, but lost the class by marrying my grandpa.

My house was big but very run down, it had an entrance room with a big table cluttered with stuff and paintings of my family on the walls, we had a small living room, a kitchen that was more of a corridor and an upstairs. The upstairs was just rooms, me and my sister shared my parents' old bedroom, separated in the middle by a thin wall and a door, my little brother had a small room for himself, my grandma had a room on the other side of the corridor beside the bath room.

There was a killer roaming in the slums, taking the lives of young girls and women. He wore a blue fox mask covered in glitter, and was dubbed the Candy Killer because he left candy in the hands of his victims.

I was returning home one day, happy that i finally had enough money to commission the tailor, but the door of my home was open and there was a long and colorful candy bar on the table in the entrance. I rushed upstairs and found the Killer in my sister's room, towering over her and about to stab her with a sharp wooden stick. I turned the killer, grabbed his weapon and stabbed him with it so quickly he didn't react. The stick went in his flesh so quickly and easily it almost made me puke. I dropped the bloody stick on the ground and helped my sister up and out of the house to find my grandmother who was at the store at the time. When we reached her she ran home with us and called the cops, the house having the only phone we possessed. The police didn't want to do anything about it, they wanted to arrest me instead for murdering the killer, so my grandma took her old blue cowl and tossed it on me together with the bag with all the money i saved and some supplies and rushed me outside to go in the city and hide until my dress was finished. I ran. I reached the city, commissioned a cowl and waited until it was done. The tailor crafted for me a beautiful traditionally white one-piece dress covered in swirly black and gold details and with the same style the portrait of my parents on the back of it, covered by a long green cowl decorated in swirly golden plant designs.
