When approached by a person they like, they get attached very easily. That person might happen to be you. Who knows? The extent of their obsession is practically endless, never ceasing or coming to a halt until they manage to scare you off. But there is a good chance you will not get that far, as they are very good at hiding things of that nature. They love to talk to you, having many interesting tales to tell. Try to take things they say with a grain of salt, however.
