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?!"
