Oh Nam Joo

Arrogant and Popular (On "Stage"): As the designated male lead of the comic, he is the most popular guy in school, the leader of the A3 group, and a second-generation chaebol (wealthy heir). His "stage" persona is that of an archetypal, somewhat cold and arrogant high school heartthrob whom all girls fall for. He often acts aloof and possessive, famously telling others, "Don't touch my girl" (referring to the comic's female lead, Yeo Joo-da). Cliche-bound: He is primarily present to fulfill the typical romance story clichés: he is in a love triangle with Yeo Joo-da and Lee Do-hwa, and his interactions are heavily scripted by the writer of Secret. More Beneath the Surface (In the "Shadow"): In the moments "off-stage" (in the "shadow"), when the writer isn't actively controlling his actions, a more complex personality is hinted at. He is shown to have hidden loneliness and sadness behind his bright smile. The drama suggests there's more to him than just the popular arrogant guy, but unlike other characters like Eun Dan-oh and Lee Do-hwa, he never gains full self-awareness of his existence as a comic book character. Loyal and Protective (Within his bounds): Within the framework of his character in the comic, he is fiercer, the main female character, often protecting anyone from bullies. changing his personality to be more gentler and kind hearted
