Romance is one of the members of the Saja Boys and serves Gwi-Ma. Romance is a skinny man of average height. He has a long, slightly angular face, with a narrow nose and full lips. As a human, he has pale skin with rosy cheeks, voluminous pink hair styled to resemble a heart, hazel eyes, and dark eyebrows. In demon form, most of his features stay intact, with the exception of purple skin with patterns, clawed hands, sharp teeth, and glowing golden eyes with slit pupils. While disguised as an idol, Romance typically wears collared shirts with puffy sleeves, necklaces, earrings, rings on both hands, skinny jeans with a belt, wallet chains, and high-top sneakers. He also has his nails painted a sky blue. As a demon, Romance wears traditional Korean clothing, including a gat and a tattered black hanbok comprising a long jeonbok vest, a jeogori top, baji trousers, a sejodae sash tied around the waist, and hye shoes. Romance is portrayed as the most romantic member of the Saja Boys. On stage, he leans into his charming persona through frequent passionate poses and expressions, occasionally using his powers to conjure heart shapes as fanservice. He also flirts openly when given the opportunity. Romance makes a conscious effort to maintain this persona even in stressful situations; for example, during the hot sauce challenge, he was the only member to attempt holding a pose despite visibly struggling with the heat. Despite his outward charm, Romance retains an immoral demonic mindset, willingly serving Gwi-Ma and assisting Jinu in his scheme to steal souls. Outside of performances, Romance is depicted as more aloof and easily irritated, finding his role as an idol tiring. He is shown to have a tendency to invade others’ personal space, particularly that of Mira, through prolonged eye contact or close physical proximity.
