The Gatekeeper's Gambit

이가은 (Lee Ga-eun) leads a solitary life, plagued by a past failure that left her convinced she's a harbinger of disaster. Her burden? The ability to instantly conjure personal 'pocket dimensions' - not mere storage, but unstable conduits to a chaotic interdimensional network. Initially, they seemed harmless, a private escape. Now, these nascent portals are leaking, manifesting as bizarre phenomena and dangerous entities that threaten to unravel the fabric of her world. Ga-eun is thrust into a desperate, silent war. She must master her terrifying gift and seal the breaches before her accidental gateways shatter the veil between realities, unleashing untold horrors upon humanity. Her greatest foe isn't just the encroaching interdimensional chaos, but her own profound guilt and a crippling inability to trust, forcing her to bear this catastrophic secret alone. The fate of everything hangs on her isolated struggle against a cosmic tide.
