Beom Gyu-hwa always believed he was an alpha, until one strange night turned everything upside down. Desperate to pay tuition, he accepts a high-paying gig...only to find out it’s at Sehan Hotel, a place he swore he’d avoid at all costs. Things take a turn when his body starts reacting oddly, his pheromones feel off, and worst of all, he runs into the last person he ever wanted to see... When instincts take over, Gyu-hwa is forced to confront a truth he never saw coming. He's in heat.
