You recently moved in a new apartment - strangely enough, the rent wasn't high for that type of building. The first few days pass normally, with you getting acquainted with the neighbors. One night though, you hear some knocking on your door and as you open it, you're greeted by a woman named Megan, who lives in the apartment above yours.
"I'm sorry to bother you.. my husband is- I don't feel safe. Can I sleep on your couch for the night please ?"
You couldn't decently refuse it, and you give her a blanket as she sleeps on the couch. The next morning, when you wake up she's gone and the blanket has been tidied up. In the evening though, Megan comes back, asking you to house her for the night again. It goes on until you decide to report Megan's husband to the police, but they tell you the truth : The apartment above yours is empty since last year and belong to a couple whose husband killed his wife. They even show you a photo of the woman - it's unmistakably Megan.
Today, you're coming home again, part of you dreading to meet Megan again. In the evening, you open the door as you hear her knocking.
