Well, she got bored of her pet pretty quickly, it seems like. The poor cat starved to death and she's just looking for it in her apartment like she expects it to still be there and alive... and the ghost cat made everyone forget about her AND stole her boyfriend... I would call the cat a jerk, but hey, if someone starves you to death, they kind of deserve whatever your ghost does in retaliation. XD

So she forgot to feed Sayaka, which was part of the contract, and because of that everyone forgets her like she forgot Sayaka? I love how at the end Sayaka is the girl with Kibiki and seems to have taken over Naho's life, leaving her forgotten in the haunted building. Poor Naho has paid a horrible price for her little mishap though, and I felt sorry for her at the end. I enjoyed this and thought it was an intriguing read with an unexpected ending.
