Evan Arclight lives in the world of illegal street racing, where control, speed, and distance are the only rules that keep him intact. On neon-lit roads and wet asphalt, he knows how to push a machine to its limit. Off the streets, he applies the same discipline to his life-never linger, never rely, never stay long enough for anything to hurt.

Arcy Veyne has never believed in pretending that emotions can be managed away. Quietly warm and emotionally steady, she represents the life Evan keeps walking away from, not because he doesn't care, but because staying has always felt more dangerous than leaving.

When circumstances force Evan to slow down and confront the life he has been avoiding, their relationship is pulled back into a space charged with unspoken history. Between late-night routines, familiar silences, and the lingering pull of the racing world, Evan faces a choice he has never trained for: whether to keep running, or finally remain.

Redline Hearts is a contemporary romance about love under restraint, intimacy shaped by denial, and the quiet courage it takes to choose something that feels normal when chaos has always been easier. A grounded, character-driven story where adrenaline and domestic life collide-and where staying becomes the bravest decision of all.
