Looks like a bloody rose in Stephen King.

The protagonist of this film tells a horrible story. Dr. Joyce Bin Laden, a professor of music psychology, led a group of people with psychic abilities into an abandoned castle called Blood Rose. She wants to inherit the spirit of her predecessor Aaron and solve the mystery that people who live here have died one after another.

If the landlord can understand English and introduce it in English, the ending should be similar to what you said, only one person survived.
