Okay as I take a break from writing for a moment I decided to yap about my Yandere Hollow Knight x Reader AU.
So the AU starts with the Reader (who I'm referring to as MC for this post from now on) discovering a glowing white rope and an ancient map that they realize they can use to find a cavern to descend into the Earth and enter a whole new world, and then safely leave said world.
This world is the world Hollow Knight and Silksong take place in.
However, rather than arriving during the time of the Infection and the Knight's journey, MC ends up arriving right when the Pale King is created, quite literally stumbling upon him when he's first trying to start his kingdom.
And eventually, a friendship forms between the two.
The world where Hollownest resides has time move significantly faster than it does in MC's world. So while MC can stay in Hollownest for what is in that world a hundred years or more, MC can then return to their own world with merely a night having passed. This leads to MC "disappearing" for long periods of time and then returning and staying for hundreds of years as if nothing happened, and- paired with the fact that humans do not necessarily exist in Hollownest or anywhere else in this world- MC is viewed as a mysterious godly being.
Of course, MC does things like wear a mask to fit in with bugs, and does many things within Hollownest as the Pale King's most trusted ally and negotiator. It is their job to travel through Hollownest and neighboring kingdoms to form alliances and such. This leads to them doing things ranging from forming a close friendship with the Traitor Lord (before he was... well... the Traitor Lord) and being kidnapped by Weavers in Deepnest multiple times.
They are there as Hollownest develops, and they- unwittingly- are having more and more bugs become yandere for them as MC, being a human, unknowing releases pheromones that quite literally mess with the minds of bugs so they gradually grow more and more obsessed with MC.
And it's especially obvious in ones MC is close to. Namely the Pale King and White Lady (she does marry the Pale King while MC is off in the human world, and then the moment MC shows up her immediate reaction is making MC the third to the relationship of the White Lady and Pale King).
And it all grows worse when the infection appears and starts to spread. Especially when the Radiance offers a deal to stop the Infection entirely as long as they get to keep MC, and the Pale King absolutely tweaks.
It leads to him destroying the artifact MC uses to return home when they voice complaints about his plan to make a Hollow Vessel, knowing how the game turns out.
So MC is essentially trapped, growing more and more scared in this world, and helplessly watching the Pure Vessel grow drastically over such a short period of time, with them only having slight bits of relief from people like the child Hornet (who in this AU was a very spunky child who insisted she was going to marry MC when she grew up) and Monomon and Quirrel.
Eventually, MC snaps and descends into the Abyss, coming across the Knight with a cracked mask, the only living vessel in the Abyss. MC responds by taking the Knight out of the Abyss, being slightly corrupted by Void in the process, healing their mask, and fleeing Hollownest with the Knight as the Pure Vessel (with both the idea that it must be as hollow as it can to make the Pale King proud and a love for MC ingrained into it).
MC and the Knight (who I'll just call Ghost) then travel throughout this world together, MC now constantly questioning if they truly are human or not anymore with all the changes they've faced.
But eventually, Ghost is called to return to Hollownest by the Vessel. And MC, even if hesitantly, follows them there.
Then we are launched into the main game, where more yandere shenanigans and more trauma ensues.
Don't even get me started on what happens in Silksong.
