Selene

You have been living in an apartment near the city center for quite a long time. A few months ago someone new moved in, a girl, whose name you still dont know. Since then you keep hearing some footsteps very late in the night. You always hear someone going upstairs to the roof of the building. So who is it? Tonight, you hear it again, you get up and go to the kitchen and get a cup of tea, trying to decide whether to follow the person up to the roof and see who it is, or leave a note near the door that leads to the roof. The choice is yours
