This is a billy and many fan fiction. Yes, their personalities do change due to age and it take a little bit more of a serious note. But enjoy c:

(The Grim Adventures of Billy and Mandy) It's 1994, and Billy and Mandy are starting seventh grade. There are a few developments, though. Billy is suddenly class heartthrob (but still dumb as a rock). Mandy's will is colliding with her hormones (but she's as evil as ever). And Grim? He can barely believe these pubescent...things are the same kids he met two years ago. But Endsville is still as strange and supernatural as ever.

Lincoln and Ronnie Anne go on their date until Ronnie Anne's friends talk about Lincoln and how she can do better. How will Lincoln react?
