The second story in this collection has a story of its own, it's just repeated in this book. If you've read the other works by this author then you would understand why the third story was confusing. Also, it felt like the first story was left unfinished. Quite disappointed in this one, but there is some quality to it (I loved the first story and want more ;-;)
