life after Heathers

To be fair, I’m a complete noob at watching musicals and slime tutorials. I recently watched Heathers and it has had me in a complete chokehold these past couple of days. I’ve watched two different casts and the film, but I long for more of the feeling that this show has given me. Are there any good suggestions to what musicals I could watch that are similar to Heathers, with main plots like romance and/or slasher? So far I’ve only seen Nerdy Prudes Must Die, which was alright imo. If there’s any book or film suggestions, I’ll take those too!
