I am really forgetful so please help me with this.

Hi guys!? there is a manwha (I forgot the title), I just read the summary and it is all about the girl who move in to an apartment. She finds a room for rent that is kinda cheap but the landlady warns her that the place is haunted. Then after she move in, there is a guy (either a ghost or whatever) that surprisingly beautiful guy. That's it and I really really want to read it badly but I don't know the title.
