After reading "The Professor's Twin Daughters" by Feng Song, I thought the subject matter was very fresh. So I decided to use the past life setting of Feng Song's characters, a pair of good friends who are better than twins, to write a fanfic of my own.
They are good friends who eat and live together, dress the same, and even have the same hobbies. They traveled to the world of HP and became twins born out of an accident that was not an accident. With the magical power as compensation, they began a new life of protecting their father and fighting against Lao Fu. (Not a father-daughter story)
