You do realize that nearly everything of what you pointed out is the basic plot of nearly every high school romance TV show, Movie, Game, even books, which is what I followed. It's a basic story line for high school media, down to the pool scene and even dodgeball. Just about everybody played dodgeball in high school. I used things from my own time in high school as well as parts of the plot too.
So what I can point out that isn't part of the main plot point to most high school media is
>The names are done that way on purpose, yes to be a funny pun on a name and have a similarity to the Snoot lore which is done in other Snoot Likes, not just mine.
>They don't race past one another, they do interact (even if its brief) in Wani they don't say a word to one another for a good portion of the beginning chapter, when in DTT when they meet its at lunch and not in class. She doesn't even realize Un is there.
>If you're going to look at someone and attempt to meet them for the first time, its going to be in the eyes. That's a standard human traight.
>I used my actual high school gym coach as a reference for Coach. He was a total dick when we're actually doing something, but when it's chill time he's pretty nice. Solly doesn't have a lot of kind moments, they're there granted, but Coach is shown as a lot nicer.
>Wani they meet in Art class, not history. DTT they officially meet at lunch.
>Un never actually defends Trinity, he realizes that if they go down to her level then they're no better than her. Danny actually talks about how much she deserves it but likes that Un didn't go through with it.
>The Teacher Mentor thing, although a less used plot point in classic high school media is an experience I used from my own high school days. I had a teacher who was a mentor to me and helped me through things. Fun Fact, he also wanted to be a dancer which is where I got my inspiration for Willz character even down to the look(besides the leotard)
Other than that, everything else is a main romance high school plot point in a ton of media.
Comparing the characters could also be done with, again, a ton of high school media.
If you're implying I "stole" from Wani, you're also implying that they stole from other media, and that media stole from another, and another, and I'm sure you can see where I'm going. So I can 100% say I did not steal from Wani. It's my first project, so I went with a basic set of plot points from what I know, mixing in with real life experiences.
