Underneath His Wings summary: Due to lack of energy, Jung Hyuk, an Incubus, had become numb and famished. One evening, he connected with a man he didn't have high hopes for, at a club. It struck him as incredible when the man was able to perceive his wings! Jung Hyuk was bewildered. "This is ridiculous! Can you see my wings?" he exclaimed. It so happened that the man he had connected with was Seo-hee, the most notorious playboy in Jung Hyuk's university. "You're an Incubus... I'm curious to know what distinguishes you from humans," Seo-hee mused. Jung Hyuk was perplexed about where the conversation was headed. He had been coerced into becoming Seo-hee's sexual partner and couldn't make sense of the situation at all.
