Ijung Naseon

Kang Yi-Chae, a second-year master's student in a notoriously tense graduate lab. Overwhelmed by work and her single-minded personality, every day is a constant strain. The only thing keeping her going is her boyfriend, Seong Ju-Won. She feels increasingly burdened by the thought that she might be becoming too dependent on him—a man who seems perfect to anyone who sees him. But with nowhere to confide these feelings, her only solace comes from the shaman So-Yul. Then one day, circumstances reveal that the very person who cornered Yi-Chae is none other than Ju-Won... As Ju-Won begins to shed his mask and actively seeks to dominate Yi-Chae, and So-Yul fights to protect her from him, what will become of Yi-Chae's future...? (Source: Naver, translated)
