Harry Potter: Bound by the Red Thread

It's a bit weird, so messy! The protagonist in the plot met Severus when he was 11 years old when he first entered school. But when they were 11 years old, Severus and Lily were still good friends. James and Severus hadn't met yet. Let's say it's already next semester. Then it is impossible for Severus and Lily to break up in half a semester, but the beginning of the plot is that Severus walked into the protagonist's box alone, and then James saw Severus mocking him severely. Then Sirius pulled James and said he was going to find Lily. What a weird timeline. There is also a blood pact involving Dumbledore. Well, at least it has nothing to do with Dumbledore and Grindelwald in the early stages. I just watched the beginning. So weird
