They were each other's first love. And their first heartbreak. Felix and Hyunjin haven't spoken since high school-since one goodbye tore them apart. Now they're debuting in the same idol group. To the world, they're rivals. Strangers. Behind closed doors, they're something messier. Bitten-back words. Lingering stares. A history neither of them knows how to bury. But feelings don't fade just because time passes. And love doesn't always listen to reason. Because what do you do when the boy you thought you lost forever... is standing right in front of you again? This is their second first love. And maybe-just maybe-it's the one that lasts.

Five years ago, Lee Felix walked away from a love that felt like a wildfire, leaving Hwang Hyunjin amidst the ashes. Now, the fire is back, but it's no longer warm-it's destructive. To save his family from financial ruin, Felix is forced into an arranged marriage with the man he once broke. Hyunjin is no longer the boy who begged him to stay; he is a cold-blooded CEO with a dominant scent that commands submission and a heart that beats for revenge. In a house filled with expensive silence and toxic pheromones, Felix must navigate a marriage that feels more like a prison sentence. The knot is tied, the vows are spoken, but in this house, there is no love-only the debt that must be paid in skin and tears. ________
