So far I think Akari did it. I think that because at the begining of the story she wasn't talking about it. And more so she was changing the subject with a common topic.

wow this was reallyyy good. I hope to see more. I just posted my first chapter of my new mystery. Fourteen days 'till death. I guess great minds think alike. But your story is wayyyy better than mine so can you read it and give me some tips?
