Zenith Gym

Beneath the bustling streets of Seoul, where the city's vibrant pulse thrives, an enigmatic subterranean arena exists—one that goes by the three-letter name "Zen." In this concealed world, raw talent and unbridled ambition converge in battles that transcend the limits of ordinary competition. The story begins with Suho Seong, the reigning champion of Zen, whose formidable reputation precedes him. The tranquility of his life is shattered when a group of students from Seongbuk High School recklessly provokes him and his friends, unaware of the immense power lurking within Suho. Amid the neon-lit alleyways and dimly lit tunnels, a street brawl ensues, drawing a curious crowd into the shadows. Suho Seong showcases his unparalleled prowess, swiftly defeating his adversaries and leaving them humbled in his wake. Yet, among the fallen, one figure stands resolute—Jin-ho, a young high school student, driven by an unspoken determination to prove himself. What begins as an unexpected clash between rivals soon takes a fateful turn. Suho's martial prowess and precise strikes overpower Jin-ho, culminating in Jin-ho's unconsciousness on the cold, unforgiving ground. It is at this vulnerable juncture that the mysterious CEO of Zen intervenes, placing a cryptic card on Jin-ho's forehead—an unspoken invitation into a world veiled in secrecy, strength, and ambition.
