Haeryun Academy

When a covert experiment at South Korea’s elite Haeryun Academy goes horrifyingly wrong, four prodigies—reclusive mathematician Shin Jae‑hyun, royal‑born scholar Park Seo‑yeon, tormented athlete Lee Min‑woo, and biotech wunderkind Kim Ha‑neul—must band together as the academy’s gilded halls give way to a ravenous undead uprising. Bound by secrets, fierce loyalties, and forbidden sparks of romance, they race through shadowed corridors and ancient mysteries to uncover the truth behind the plague—and discover that saving their world may demand the ultimate sacrifice.
