So, the one thing about FanFiction is that it doesn't really let you extensively tag anything, so I've posted this as well on AO3 and these are the tags I used (yes, some of them aren't real tags)

Relationships: Jason "J. D." Dean/Veronica Sawyer, Heather Chandler/Heather McNamara, Kurt Kelly/Ram Sweeney, Jason "J.D." Dean & Heather McNamara, Heather Chandler & Veronica Sawyer, Heather McNamara & Veronica Sawyer, Martha Dunnstock & Veronica Sawyer

Characters: Veronica Sawyer, Jason "J. D." Dean, Heather Chandler (Heathers), Heather McNamara. Heather Duke, Martha Dunnstock, Ram Sweeney, Kurt Kelly

Additional Tags: Female Friendship, Male Friendship, Male-Female Friendship, They're all friends it's pretty cute, Implied/Referenced Suicide Cutting, they're in like a psyciatric ward for at risk teens, Unreliable Narrator, Everyone is Heathers the musical, except for JD who's Christian Slater in my mind for some reason, Don't ask me why, I don't know, He just is, Ryan McCartan just isn't wiry enough I guess, Other Additional Tags to Be Added, Tags May Change, Not Beta Read

Also part of the summary I couldn't add:

(Veronica has antisocial problems she won't admit to, Heather is kind of OCD and has a really bad head-space about needing to be perfect all the time, Heather basically has anorexia, Heather has sever depression, Martha's secretly depressed and insecure, Kurt has anxiety, Ram's dad is a homophobe, and JD... JD just has a lot of problems like always)
