Project PARAGON

At a prestigious university in Seoul, four students-Su-bin, Woo-ri, Hye-ri, and Hye-won-appear to lead ordinary, privileged lives, but each carries a dark legacy shrouded in secrets that could unravel the very fabric of their world.

Su-bin, the enigmatic daughter of the head of Prime Medical Center, is more than just a brilliant student-she's a product of a dangerous genetic experiment, carrying within her the potential for both salvation and destruction. Woo-ri, the intelligent daughter of powerful lawyers from Aegis Law Firm, unknowingly holds the key to a vaccine that could either save humanity or bring about its downfall. Hye-ri and Hye-won, heirs to the cutting-edge pharmaceutical company Genexis Pharma, begin to uncover the truth about their father-a man everyone believed was simply a rogue scientist.

But the true threat isn't their parents-it's Umbra Core, a shadowy organization of brilliant but corrupted geneticists, hiding under the guise of 미래유전연구원 (Mirae Yujeon Yeonguwon). Their goal: to weaponize genetic research, seize control over Su-bin and Hye-won's unique genetic makeup, and exploit the vaccine that Woo-ri carries.

Amid this chaos, an unexpected and forbidden romance begins to blossom between Su-bin and Hye-ri, two women bound by their shared secrets and the dangerous truths of their families. As the lines between enemies and allies blur, their connection deepens, sparking a passionate relationship that is as perilous as it is inevitable. Their love becomes a weapon in its own right, one that could either save or doom them.

As the conspiracy unfolds and the stakes rise, the students must grapple with the truth of who they really are, what they are capable of, and how far they are willing to go to protect the ones they love-especially when they realize they might be the cure... or the weapon that will destroy everything.
