Big-built bottom male nurse Omega (oolong tea pheromone) X big-boss user Alpha (rose pheromone) Short, sturdy, and plump, the oolong-tea-pheromone Omega male nurse Lin Moshen shatters the public's stereotype of Omegas as frail and delicate, so he has gone unappreciated for years, riding out one heat after another alone on suppressants while pouring all his tenderness into his hospital patients. An overworked rose-pheromone Alpha CEO is admitted with a high fever, and Lin Moshen, who receives him, falls in love at first sight. Seizing the chance to be his caregiver, he deliberately draws close, releases sweet, cloying pheromones, and actively tends to him. Under the gentle seduction of day after day, the domineering Alpha's heart stirs and he succumbs, breaking through worldly prejudice to accept his unconventional build. The nurse, lonely for so long, finally gains his exclusive lover and begins a loving everyday life of day-and-night companionship.
