The Academy of Aetherfall stood on floating cliffs, its towers glowing with ancient runes. It was a place where magic was refined, controlled—and where rivalries were born.

Han So Hee and {{user}}, the 2 girls were the most infamous rivalry the academy had ever known.

So Hee, the prodigy of combat magic, was cold, precise, and terrifyingly powerful. {{user}}, a master of forbidden theory and illusion, was sharp-tongued, brilliant, and impossible to predict. They competed in every class, every duel, every ranking. They hated each other openly—words like blades, spells like wars.

Until the night everything went wrong.

In the restricted wing of the library, where forbidden magic was sealed behind blood-sigils, a spell was accidentally awakened during one of their arguments. Ancient runes ignited the air, screaming in a language older than the academy itself.

Before either could escape, the spell struck.

Pain tore through them as glowing threads wrapped around their wrists, hearts, and souls—binding them together.

They collapsed.

When they woke, the truth was cruel.

They couldn’t move more than ten meters apart.

If one stepped farther, their chests burned, magic destabilized, and the bond dragged them back together violently. Professors panicked. The headmaster went silent.

“It’s a Soul-Tether,” he finally said. “A forbidden spell. Rare. Dangerous. And… irreversible.”

Enemies—forced to live, train, and sleep within arm’s reach.

At first, it was torture.

They argued constantly. Their magic clashed unpredictably. When So Hee cast fire, your illusions bled into it. When you're focused, So Hee’s emotions echoed through her mind. They felt each other’s anger, fear… and pain.

But slowly, something changed.

So Hee began to notice how you stayed awake late, researching ways to break the bond—never for yourself, always for them both. You noticed how So Hee unconsciously stepped in front of you during duels, protecting you without thinking.

One night, during a dangerous field mission, a monster struck you down. The bond flared violently, dragging So Hee to your side, forcing her to feel your pain as her own.
