T E N S I O N | Seonghyeon - Rora |Ft. Other Ships with Cortis|

"You can't buy me, and you certainly can't break me."

Shinwa Elite High Academy is an ivory cage built exclusively for the children of the one percent-a world governed by old money, untouchable status, and TBRD (The Great Brilliant Dragons), a ruthless 10,000-man syndicate that rules the city's underground. The academy's fragile hierarchy faces an unprecedented disruption when five fiercely intelligent scholarship students win the annual grant exams, refusing to bow to the school's wealthy elite.
At the center of the clash is Lee Dain (Rora), a brilliant, hyper-observant 18-year-old whose sharp tongue and blistering sarcasm make her an instant target. She has no interest in high-society games, but when her friends are threatened, her protective rage knows no bounds. Her defiance immediately draws the toxic, hyper-focused attention of Om Seonghyeon (Sean), the volatile, icy leader of TBRD and the academy's top benefactor.

Sean is used to absolute submission, controlling everything through fear, adrenaline, and midnight street races. Yet, he finds himself dangerously paralyzed by a girl he cannot manipulate, bribe, or intimidate. Forced into an intensive, year-long academic partnership, their initial hatred sparks a suffocating psychological warfare. As external syndicate wars escalate and personal boundaries blur, Sean's fixation spirals into a dark, burning obsession. In a world where status is weaponized, Tension explores the dangerous thin line between absolute animosity and unshakeable, possessive devotion.
