Harry Potter: Transmigrating to the Generation Before His Parents

I just read the first few chapters, and I felt that there were really no plot twists in the early stages, or it was like "Harry must be careful not to reveal any flaws next time" or something like that, and the time narration was also quite simple, "once, once, at a time..., As time went by" This is no different from reading the text, and then the time jumps very quickly, and the relationship between the Marauder, Snape and Lily has not been handled well, and there is a sentence in it that "(James) will not let (Snape) "Snape) bullies others", according to my memory, "(James) fell in love with (Lily) at first sight, and then (Lily) (Snape) was a friend from the beginning. Simply (James) was unhappy with the contact between (Snape) and (Lily), there is no such thing as (Snape) Nap) bully others." From the front, it seems that there is no focus, no main line, and no date and time line is mentioned. At least give it a spring, summer, autumn, winter, or week, otherwise it is "in a Defense Against the Dark Arts class" and "once in a herbal medicine class." The plot jumps in it are "in a Defense Against the Dark Arts class" and "there was a herbal medicine class", which is a very blunt jump.
