Several upcoming posts will address "frenemies," a common trope in romance.

One of my favorite scenes occurs in the library. Sangwoo is becoming more interested in Jaeyeong and--without consciously acknowledging his own feelings--more enamored. Eyeing Jaeyeong in the library, he mutters, "He disturbs me even when he is quiet."
In a manga, Jaeyeong would be shown with ears and a wagging tail!
