Obsession, violence, and psychological breakdowns.
War trauma, survivor's guilt, and emotional introspection.

This story has teeth.It bites.But it also heals.
Yes, love happens.Yes, girls fall for the MC.Yes, there are sweet moments...But they might be followed by a murder attempt in the janitor's closet.
Harem and Romance in a Yandere World
The protagonist—Jason Kyle M. Lecter—is not your usual rom-com lead.He's a former U.S. soldier. Broken, scarred, and sharp as hell.
He doesn't fumble over feelings.He's not dense.He sees through lies.And when a girl confesses?He doesn't blush—he calculates if she's hiding a weapon behind her back.
That's because in this world, romance is warfare.
The girls around him aren't harmless archetypes. They're rivals. Queens. Monsters in disguise. Each of them driven by obsession, emotion, or trauma. Some might love him genuinely. Others might be using him as a pawn. A few may not even know the difference themselves.
This is a harem, yes—But it's not about "collecting waifus."It's about surviving love and deciding what kind of love is worth surviving for. Reader Discretion Advised
This novel contains mature themes and situations that may be triggering or emotionally intense:
Graphic depictions of violence and murder
Dark psychological profiles
Mental instability and delusional behavior
Themes of obsession, trauma, survivor's guilt, and PTSD
Unstable relationships and possessive dynamics
Profanity and intense emotional language
Yandere behavior treated seriously—not glamorized
That said, the story does not glorify abuse or violence. While certain characters act out of obsession or trauma, their behavior is contextualized, examined, and—where possible—challenged or deconstructed.
There are also lighthearted moments, emotional bonds, and moments of healing.This is a story of growth, even if it starts with blood and blades.
About the MC:
Jason Kyle M. Lecter isn't an average boy.He's a former soldier who lost everything. Family. Friends. Comrades.
He found peace in the most unexpected place: a game—Yandere Simulator.
That peace was shattered when he got pulled into the very game that gave him escape, forced to take on the role of Lucien Kurozawa, a third-rate villain who wasn't meant to matter.
But Jason is not here to die forgotten.
He's strategic, emotionally guarded, and always three steps ahead. While other MCs get charmed, he gets suspicious. While others run, he plans. He's dealing with grief, trauma, and confusion—but he's not passive.
He doesn't want a harem.
But he might earn one anyway—not because he's lucky, but because he's the only person who sees these broken girls as more than stereotypes. He treats them like people.
And they don't know what to do with that.
Game Mechanics vs. Real Life
This story plays with dating sim tropes and then burns them alive.
You'll find:
Glitched dialogue trees.
AI breaking script.
Multiple timelines and flag resets.
Characters remembering "past routes."
A protagonist with knowledge of the entire game's system.
But now?The system doesn't work.Or maybe it's changing.And the girls?They remember things they shouldn't.
Jason is stuck in a world that looks like a game, but feels too real.Pain is real. Death is permanent. Love... might be corrupted.
And worse?He's not the only one who's self-aware.
Author's Intent:
This novel blends psychological horror, romance, action, satire, and emotional recovery.
It explores:
The line between affection and obsession.
The cost of rewriting fate.
How a background NPC can change everything.
War trauma through the lens of simulation.
And yes… the madness of yanderes.
There is comedy, especially when Jason mocks game logic or points out how absurd these girls act.There is romance, often subtle, sometimes terrifying.There is character development—including for the rivals, who are more than their yandere roles.
Some will be redeemable.Some will not.That's part of the journey.
To the Reader if you enjoy:
Stories where the MC is competent and not emotionally blind.
Exploring broken systems and corrupt simulations.
Watching manipulative characters clash with calculating protagonists.
Romance with intensity and tension.
Harem stories where not every girl is guaranteed a happy ending…
Then this story is for you.
But if you're here just for fluff, wish-fulfillment, or shallow romance?
You'll find this world a bit sharper than you expected.
Final Thought:
This novel is, above all else, about redemption.Jason is trying to find peace. Lucien is trying to escape his fate.And maybe, just maybe, some of these girls are looking for more than love.
They want someone to see them.Understand them.Save them—from themselves.
But can Jason do that…without becoming a monster himself?
Welcome to Yandere Sim.Where every smile hides a secret…And even love can kill.
