Our Untamed Hearts

🔥 Love rekindled. Secrets exposed. A city on fire.
Six years ago, Y/N walked away from Kim Namjoon-the man who broke her heart and buried her trust. Now he's back, not just as the firefighter who once loved recklessly, but as the captain leading his team into the city's deadliest disasters.
When fate throws them together again, sparks reignite. But danger isn't only in the flames. A string of "accidents" sweeps through Seoul-gas leaks, explosions, fires that don't add up. The deeper Y/N and Namjoon dig, the more they uncover: sabotage, cover-ups, and a corporation willing to silence anyone who stands in its way.
As the fires grow closer and enemies circle, Y/N must decide-protect her family and her heart, or fight beside the man she swore she'd never forgive.
Some loves are worth burning for.
And some truths are too dangerous to bury.
🔥 A slow-burn, second-chance romance meets a high-stakes thriller.
💔 Enemies in the shadows. Lovers in the line of fire.
🔥 Book One of a two-part saga.

✨Author's Note✨️
This story is inspired by the C-drama Fireworks of My Heart but is not a direct retelling. I've added my own twists, new conflicts, and deeper conspiracy arcs. The male lead is written as BTS's Kim Namjoon, and the heroine is Y/N so readers can step fully into her shoes.
Think of it as: Firefighter x Doctor romance + corporate conspiracy + emotional slow burn - my own re-imagined version, with BTS woven in.
