I found this story in my chats with my sister, so if it looks a little strange, that's why.
Yandere! Qin Shi Huang x Reader (with a twist?)
OKAY, imagine this: Reader is a young girl from Zhao who was forced into servitude after her mother died in the Qin Clan's uprising.
But unlike everyone else, Reader doesn't actually resent Qin/Zheng. Whether it's because she's a young child, because she has no one to teach her these prejudices, or perhaps simply because, even as a child, she doesn't understand why people hate someone who had no power in the tragedy, what she feels is pity for this boy, not hatred.
Besides, he was the ONLY boy her age she could interact with, so she wanted to befriend him, especially after seeing how the rest of the world treated him. Even if Zheng was definitely somewhat skeptical at first, you can bet he was so desperate for affection that he didn't care about any suspicions about the reader.
Obviously, this makes Zheng VERY attached to the reader; she's his ONLY positive influence throughout his entire childhood. Because of this, he's VERY clingy and touchy-feely. Having grown up with this, the reader doesn't see anything wrong with it. This marks a certain bad habit of "not having boundaries" as they grow up. Not only physically, but also with certain "bad habits" of Zheng/Qin towards her.
In the two years that Zheng is cared for by Ching-yen, Qin/Zheng starts to get even closer to the reader. Taking her everywhere with him, bringing her things, even becoming violent if the reader left for too long, or worse, someone insulted her. But since the reader was already used to this (or rather, desensitized), she doesn't even see it as something bad; it's like having your own guard dog.
When Zheng is finally acknowledged by his father, reader has to stay behind with the servants, but don't worry! Zheng promises her it won't be for long!
Reader doesn't hear from Zheng for a few months, during which time she is finally taken in by another servant. She grows up, and everything seems to be going well.
However, when Reader reaches marriageable age, things take a turn for the worse, at least for everyone else.
Reader's adoptive father genuinely loves her dearly, having served with her as a servant and caring for her all her life since her mother's death. But he is also perceptive and senses that something is off about his daughter's relationship with Qin.
So when Qin comes one day demanding Reader's hand in marriage, despite all the good things it would bring, he refuses.
Obviously, Qin was initially more than prepared to resort to violence when this happened, but reader's adoptive father proposes a deal: If he achieves his goal of unifying China before Reader marries another man, then he will allow him to marry her. If he fails, or if reader marries before he does, it's game over for him.
Qin obviously finds this interesting (more because of the man's audacity than what's actually happening, but he lets it slide since he's his future father-in-law), but he sets his own conditions: 1- the adoptive father is strictly FORBIDDEN from arranging marriages with reader, 2- reader will not be aware of this arrangement, and 3- he will not restrict their communication.
Reader's adoptive father was so convinced this was a FOOLPROOF plan, because there's no way a boy could unite five different nations! And even if he miraculously could, reader is a charming lady; she'll surely find a husband without his intervention!
...at least that's what he thought.
While Qin isn't violent around Reader (at least not anymore), he would definitely get rid of any rival he sees as a potential threat to the arrangement. Whether by discreetly eliminating rivals, framing them, and making them look undesirable, etc. Yeah, he cheated, what did you expect?
Meanwhile, Reader and he maintain communication through letters! Reader is probably unknowingly giving Qin more people to "deal with" when she decides to confide in him (again, she doesn't realize, due to her lack of boundaries, that the way Qin speaks to her is more like a lover than a friend).
Years go by, and the adoptive father is growing anxious. Not only is Qin progressing in his conquest, but his daughter seems not only uninterested in marriage, but more interested in Qin than anyone else.
I think Qin would only act like a full-blown yandere if the adoptive father tries to send Reader away on a ship out of China. So he does the most sensible thing: he has the man arrested and announces his public execution (which is an excuse for Reader to come out of wherever she is and rescue her old man). He says it's just a trick to get reader out of hiding, but DAMN, the idea of getting rid of (adoptive father) and having reader only for HIM is tempting...
WHAT'S INTERESTING IS HOW THE ROLES ARE REVERSED!
Reader, in an attempt to turn the tables on him, tells Qin that he can't execute her father. The reason? That's not the way to treat your wife's relatives!
And reader even pretends to cry about how he can go around saying they're married when he treats her family in such a BARBARIC AND SHAMEFUL way.
And you know what? IT WORKED! his lovely reader is soooo right! the old man may be a pain in the ass, but its his father-in-law after all. just like they say, happy wife happy life.
I think this would be the best scenario for a Qin Shi Huang Yandere, not only because his partner is "willing" to tolerate his yandere tendencies, but also because she knows how to counter them. Fortunately, the reader knows him well enough to handle him and prevent him from being a walking nuclear bomb (at least all the time).
hope that still works after death....
