you had seen a video on TikTok of a girl using pheromone perfume to see her boyfriends reaction so you decided to try it

You went to your room to get out the perfume that your sister had gifted you on your birthday and you put it on your neck, all around

Jungwon had come home, greeting you with a smile but then suddenly bringing his lips to your neck

"Woah babe you smell so good" he said, you could feel his breath on your neck as he continued to smell you
