Dear Diary,
Today some girl approached my dear Len. She kept talking to him, and following him around... I didn't like it, so I whispered something in her ear. She laughed. Oh, how she laughed. She must have thought I was joking, because she laughed so much... Not as much as she will scream.
Author's Note: Warning: This is a yandere fanfic. So, it's not for everyone. This is one of the definitions for the word 'yandere' that I found on google: "describes an anime character who is either psychotic or violent or both, and shows affection to the main character." Of course, in this fanfic, Rin is the main character, but she has an obsession with Len.
