The Uncanny Counter (Mun x OC Fanfic)

Mi-Young and So Mun used to be best friends, until the accident that changed everything, no not So Mun's accident... the one before that, Mine... I'm Mi-Young and when I was just 5 years old I was in a horrible accident with my big brother, except... he didn't make it... But I was in a coma for almost 3 years before my 'Partner' Ara Seong found me, she explained to me the rules of being a counter and that I, Mi-Young, would be the very youngest counter to be welcomed in Yung, and that if I agreed to my duets of the job that someday, I will get to have a normal life again, so I agreed to do whatever I needed to complete my job as a counter so I could live a normal life again, so there I was, only 8 years old and starting my training and my job as a counter, if you want to know the rest of my story, you might want to stick around for a little bit, it's going to get pretty interesting, but I must also warn you that it does have it's very, how do you say, sexual scenes so if you are anyone under the age of 18, you might want to find some other story to hear...
