Heat Protectant

Su Seong-Hyeon, a successful hair designer, has been secretly in love with his best friend, Jeong Jun-Yeon. One day, Jun-Yeon asks Seong-Hyeon to tutor his younger brother, Jae-Yeon. While Seong-Hyeon believes Jae-Yeon to be a Beta, he starts to faintly sense pheromones from him. Then, one day, Seong-Hyeon discovers a piece of clothing soaked in pheromones among the gifts he received from Jae-Yeon. Overcome by the pheromones, he experiences an unusual heat. At that moment, while on a call with Jun-Yeon, he ends up pleasuring himself to the sound of his voice...

"What kind of insane Omega spreads their pheromones like this?!"
