From Naughty

In the past, Tae-Hee dreamed of the entertainment industry while watching the famous actor Hwa-Won. However, the object of his admiration that he met after debuting as an idol was quite different from his expectations. Seeing the disappointing appearance of Hwa-Won, who had fallen into a period of boredom and stagnation, Tae-Hee inadvertently made a remark that crossed the line, saying, "The Hwa-Won I've seen wasn't like this." This remark soon ignites their relationship...!

"Tae-Hee, you've never had sex, right? There's nothing you can do. A junior who is lacking has no choice but to be educated by a senior."
