It's very common in casual sex between Japanese and Chinese people to use drugs that increase sexual desire, but I've never seen it in Korean manhwa. I thought it was the same reason, but now discovering the side effects of the drug, your theory is interesting too
I kinda understand the author intention with the drug. I guess the author want to make it lil realistic. I means it's would be weird that they're in shabby business but never involved in drugs. I guess author watch Jubilee or smthng loll jkjk
I had a friend who is partyer, open to initiate sex topic and even got some sugar daddy. So, I assumed this is where the author got the idea. Guess they have a friend or they saw news and wa la!
