Another World // Yandere x *Astronaut* Reader

(I have parts written, but it shows a 0. I'm comfused. Like on another one of my stories I have 4 parts, but it says I have 1.) A young astronaut named (Y/n) works for NASA. She helps them discover new worlds. Or should I say, universes. One day she went to another universe and crash landed. Now she has to blend in with the crowd. Little did she know that someone was watching her the whole time.
