A Sudden Change In Time

This is a Harry Potter fanfiction story. It is about the Marauders have discovered a spell that can go travel in time. This spell transported them in the exact same time in Harry's fourth year, that includes the Triwizard Tournament. What will they do if they knew what happened in their futures?

And I'm warning you, there would be a character added but if you want, you could be her, yup, like 'x reader'. (If you're a girl)

For short, it would be a 'Marauders in the future' and "Harry Potter love story (or whatever they called it)'.

Update: So I published this work back in 2017, and this is 2020 me coming to say hello to the people who have read and will read this story. I really appreciate that you are giving this story into consideration. Reading it now, I realized how bad of a writer I was and I humbly apologize for the grammar mistakes and sentences that sounded awkward lmao
