I think i've hit the point where I'm done asking how anyone can enjoy reading this, so now I'm gonna ask; How can Lily find any joy in writing this. Is the idea of angering ReyLo's that inspiring?
It's pretty common among immature authors.
Immature authors -- especially younger ones -- tend to think that, since they're in charge of a story, they can do whatever they want. They wind up putting a lot of themselves in their characters -- or wind up making the characters the selves they desperately want to be -- and in turn make the villains in their story based on 'enemies' they have in real life. Even if they're writing fanfiction they'll wind up putting their own quirks and personality traits on characters they identify with (or want to be), and twist the villains into caricatures of who and what they hate.
They wind up writing stories with no real understanding of buildup and payoff, letting the main characters win with little to no effort, making the villains comically evil, or else going full edgelord and doing the same thing but making it dark and brooding.
It's something that younger or grossly inexperienced writers do because they understand the shallowest beats of a story but don't fully understand how to implement them. They think that instant gratification is preferable to tension because, being young and impatient, it's what they want to see, and they've probably wondered 'well if X character is so powerful why don't they just kill the bad guys immediately?' They write by aping what they already like, but only aping the
parts that they already like, so you get stories where it's almost nothing but introducing conflict and then immediately resolving conflict because those are the things that they most remember. Or the parts that they most enjoy.
Honestly there's nothing wrong with getting your feet wet by doing this. A lot of people try their hand at writing when they're young teenagers and have a lot of free time and ideas they want to try out, and while it's generally
bad writing, it's understandable-- they need to learn, and there's no better place to start than just trying. They'll be proud of what they made for a while (and possibly extremely defensive), but as they get older and continue reading and consuming other media, they'll start to realize that their older works are lacking something. They'll start examining how to better ease into events. They'll start making deeper characters and examining themes. They'll start realizing that it's not satisfying to just introduce a conflict and then reveal that the main character actually knows exactly how to solve it; they'll realize that it's more fulfilling, both for the audience and for the writer, to actually have the character struggle and overcome.
Lily is an immature writer. She's still in that phase where writing is about instant gratification, where any conflicts set up are resolved almost immediately or else ignored and never brought up again. She writes whatever comes to her head because it's something she wants to do, because she hasn't gotten out of that mindset that you just write the Good Parts and the parts in between -- building tension, building characters, laying the groundwork of the environment -- are just unnecessary filler between the Good Parts. It's satisfying in an immediate sense, but as I said, most people who continue to pursue writing will realize quickly that it's
much more satisfying to actually have to struggle and overcome against conflict, and will gradually grow out of this instant gratification phase.
I say 'immature writers' rather than 'young writers' because people who don't really get into writing until they're older aren't necessarily going to go in with all this knowledge behind them, either. There's a lot of theory behind writing and narrative construction, but as with any art form you need practice in order to get the story to work the way you want it to. You can discuss tension building until the cows come home, but actually sitting down and figuring out how to do it a very different thing, and immature writers -- even those doing their best, with all the knowledge behind them -- generally just won't have a full grasp on it.
However, I also say 'immature' because that's very much the mindset on display here. Lily's writing regarding Kylo and whatever other characters she doesn't like amounts to a child's concept of revenge. It's not about the heroes overcoming, it's about humiliating a schoolyard bully. It's about bashing action figures into each other and then dunking Kylo Ren's head into a toilet while yelling "Take that!" Again, a hallmark of immature writing, more prevalent when the writer is also an immature personality. Common among younger writers who just don't have the life experience. Common among man-children, too.
That's the satisfaction Lily gets out of this. She builds up a straw villain so she can stomp on him and make fun of him and 'win'. It's a purely childish response and a purely instinctual glee. She just wants the 'good parts', without realizing that those parts are only good because of everything else around them.
