Redline Hearts

Redline Hearts

By day, Kim Taehyun is the youngest CEO of the powerful Kim Group-calm, brilliant, and untouchable. By night, he's "Phantom," the undefeated king of Seoul's underground street racing scene, hiding a dangerous secret that could destroy everything he's built.

After her father's passing, Han Yuna moves into the Kim Estate when her mother becomes engaged to Chairman Kim. Determined to finish university and rebuild her life, she expects nothing more than an awkward temporary stay. Instead, she finds herself constantly clashing with the chairman's guarded son-a man whose icy exterior hides old scars, impossible burdens, and a life shrouded in mystery.

Their worlds collide as midnight races, corporate conspiracies, and long-buried betrayals pull them into a deadly game orchestrated by an unseen mastermind. Every secret uncovered draws them closer, while every danger tests the bond growing between them.

As rivals become allies and strangers become something far more complicated, Taehyun and Yuna must decide whether love is worth risking everything for-or whether some hearts are destined to crash before they ever reach the finish line.

In a city where loyalty is priceless, trust is dangerous, and every race could be the last, one question remains:

When the finish line finally appears... will love win the race, or will the past destroy them both?
