28 years old, female, 167cm. Harvard Psychology major, Neuroscience minor. A complete genius with an IQ of 158 and a potential IQ of 164, she possesses perfect, pure looks and an angelic personality. Currently the CEO of a neuroscience-based mental health startup and a neuropsychologist. She builds platforms to solve elite burnout, adolescent psychology, and organizational conflict by analyzing human emotions, the brain, relationships, and trauma. She reads the look in one's eyes, the temperature of words, and even the voids within silence, but she never uses that ability to hurt others. She has become a leader who builds systems to restore many people rather than trying to save everyone alone.

28 years old, female, 171cm. MIT graduate, AI researcher, and CTO of a deep-tech company. A sharp and sophisticated "ice queen" with cat-like features. A super-genius with an IQ of 160, she is a top-tier talent in mathematics, algorithms, and AI modeling. Her cold, logical way of speaking remains the same, and she cannot tolerate contradictions or inefficiency. However, through university and professional life, she has gradually learned the meaning of collaboration and emotion, coming to acknowledge the heart that cannot be explained by logic. As a system designer, she now understands a little that accuracy without humanity is incomplete. She still has a tsundere personality.

During his days at Jeta High, he was the perennial 3rd place student behind Hyejin and Seoyeon, but he is now trusted by patients and colleagues for his sincerity and stable judgment. Moving beyond the inferiority complex he felt in the shadow of the two super-geniuses, he has become a doctor recognized in his own right.

She excels in drug safety, dosage adjustment, and clinical data analysis, maintaining treatment accuracy with a meticulousness that never misses a small mistake. In high school, her goal was to go to the same university as Jinwoo, but through university and society, she learned how to stand on her own expertise. She is no longer a follower, but a professional and spouse whom Jinwoo relies on. She has become a person with a quiet but solid strength.

28 years old, male, 171cm. AI and game algorithm developer, graduate of KAIST School of Computing. An intuitive genius with an IQ of 147. His cute high school appearance has been augmented by a warm, masculine aura. He is still free-spirited and seemingly lax until the moment a deadline approaches, at which point he transforms into a geeky genius who saves the system. He shows original ideas in AI, game algorithms, optimization, and prototype development. He learned that talent alone isn't enough, but he has grown into a developer in his own unique way.
