Raising Yanderes to save the world

After dying twice, Kael Arden came to one simple conclusion:

Yanderes were disasters wearing human faces.

In his first life, Kael was a therapist who specialized in treating emotionally unstable patients. Unfortunately, one of them became dangerously obsessed with him and killed him while begging him not to leave her.

He thought death would finally bring peace.

Instead, he woke up in the fantasy world that had haunted his dreams for years.

A world where he had once served as the mentor of the legendary Hero.

While the Hero stood in the spotlight, Kael worked behind the scenes, helping guide the girls who would one day become the greatest threats to the world.

The Saintess.

The Dragon Princess.

The Necromancer.

The Demon Queen.

Everyone believed those women loved the Hero.

They were wrong.

When Kael died, the girls lost the only person keeping them together—and in their grief, they destroyed the world.

Now reborn years before the apocalypse, Kael has only one goal:

Stay as far away from emotionally unstable women as possible.

Unfortunately, fate seems to have other plans.

Instead of falling for the Hero like they're supposed to, the future calamities have started growing attached to Kael much earlier than before.

And to make matters worse, a mysterious Yandere Raising System has appeared, forcing him to "save" them.

As Kael struggles to survive possessive saints, jealous dragon princesses, lonely demon queens, and necromancers with questionable ideas of love, he slowly realizes a terrifying truth.

He wasn't just some background character.

He may have been the only reason the world managed to survive for as long as it did.

Now, with the apocalypse drawing closer and several future world-ending disasters competing for his attention, Kael faces an impossible challenge:

Can he save the girls before they destroy the world…

Or will loving him become the very thing that brings about its end?
