Looking for a specific horror movie, please help!

Hello, I'm looking for a horror movie that I just cannot find. The plot is something like this: a student commits suicide by jumping off a building, and her dead body falls on the main protagonist while she exits said building. The ghost then begins haunting her and strange things start to happen to the main protagonist. As far as I can remember, there was an idol in the leading role :/ Your help is much appreciated!
