SYL-CHAN'S PROFILE

I'm currently playing this and I can't seem to make it out of the Library Guard's home after retrieving the key to the library (it's still pretty early in the game) without getting caught by the ghost :$

Is there some way you can run? Or am I forgetting to do something? Please help~! Otherwise, it's impossible for me to pass and I love everything about this game so far :(
