'Is it a boy or a girl'

A question that every ob-gyn can answer easily, but for Kang Seulgi's parents it was different. When her parents ask the doctor if the newborn baby is a boy or a girl the doctor cannot answer.

Seulgi was born inter, and when she turned 1 her father decided that his child is to be a boy. She grew up knowing that she is a boy until her 11th birthday when she realizes that something is different with her. 

Her father made a mistake and what worst is that the surgery is irreversible.
