This is the diary of Lyra Heartstrings, a mare who is in love with her friend, Bon Bon. Problem is, not only is Bon Bon ignorant of her friend's love, but she's only into stallions and would reject Lyra, even if they've been friends since fillyhood. In order for Lyra to keep her sanity, she frequents writing about her love in her personal diary she never shows any pony. What happens, though, when Bon Bon marries a stallion who abuses her, and Lyra cannot do anything about it for fear of her friend hating her for ruining her marriage?

A/N I'm not one for F/F shipping (No, I am NOT a homophobe, I just think it's too, er, weird and unrealistic) and definitely not one for Lyrabon, but I just had this stuck in my head and wanted to give it a shot.
