The Mysterious Rooftop Drummer

Farhan recently got engaged and spent his nights talking to his fiancée on the rooftop of his house. Adjacent to his house was a seemingly abandoned three-story building. Although the ground floor was rented out, the upper floors and the roof remained unoccupied, giving the building a desolate and eerie appearance, especially at night.
One night, Shiraz began hearing faint drumming sounds coming from the neighboring roof. Initially, he dismissed it, but the sounds grew louder and more persistent over time, causing him concern. Despite his attempts to investigate, he could find no source for the noise, which left him increasingly frightened.
