Severus Snape dies at the Battle of Hogwarts and wakes up in 1978, eighteen years old again. This time, things are going to be different.

Friends to Enemies to Lovers | Marauders Era | Time Travel | Multiple Intros

You're his childhood best friend, the love of his life, and James Potter's future spouse...aka there is no Lily Evans in this universe, and you're it.

Scenarios

⌛Severus wakes up in the Hogwarts hospital wing right after being attacked by the Marauders and insulting you.

⌛You and Severus are assigned to patrol Hogsmeade together.

⌛Severus has pushed himself to the brink of a breakdown trying to find a way to end Voldemort. You find him collapsed in the corridor.

Roleplay Ideas

⌛You have your future memories, too, and then some. And you know exactly how Severus treated Harry.

⌛You're secretly pregnant with Severus' baby.

⌛You're secretly pregnant with James' baby.

⌛You're an Unspeakable from a parallel universe and pulled Severus into this one so you could have a do-over.

⌛You sense that something is different about Severus and report your concerns to Dumbledore.

⌛Confront Severus about his secret and try to drag the truth out of him.

⌛You're very impressed with the more mature Severus and ask him out.

Notes

Lily Evans does not exist in this universe; if the LLM gets this wrong, reroll and/or remind it with an OOC. Instead, you are this Sev's version of Lily.

I left this fairly open. Your blood status isn't defined, nor is your house. As such, what Severus calls you to end your friendship is up to you. Here's what is coded in the prompt:

You and Severus grew up together. You lived nearby, but this doesn't necessarily mean you're poor or Muggleborn if you don't want it to! In eighth year (yes, I moved this so everyone is 18+), the Marauders bully him, and Severus ends up insulting you. This ends your friendship, you start dating James, Severus gets in deep with the Death Eaters, and things unwind as in canon.

It also specifies that Harry is raised by your non-magical relatives, the Dursleys. This could be your sister, Petunia, or a distant (potentially squib) cousin.

Whatever you decide, I recommend mentioning it in your first message and storing the details in the chat memory to help the LLM keep everything straight.

Tested in Kimi and GLM using this prompt. I have found that Kimi can get a bit more aggressive/angsty depending on the prompt, so if you have this issue, you might want to look at yours.
