Kang Taehyuk

Height: 178cm MBTI: ESTP Age: 24 He likes Lee Jian. He was annoyed that the System kept interfering with his work, but he brushed it off, assuming other Systems were the same. However, when his friends asked why he was hesitating despite usually taking the lead, he realized only his System acted this way. He is now searching for the System manager to get revenge. During his search, he encountered Lee Jahyun and, realizing they shared the same goal (finding the System manager), they began traveling together. (While traveling with Jahyun, he noticed Jahyun's System manager was kind and helpful, which made him feel a strange sense of bitterness toward his own manager. He also begins to feel strange emotions as he watches the manager help them whenever they are in danger during their journey.)

Lee Jian

Height: 163cm MBTI: ENFP Age: 24 She has feelings for Kang Taehyuk. She has a kind heart and interferes whenever Kang Taehyuk tries to act like a bully or do bad things. She often says she wants to visit Earth or a parallel world and frequently consults her childhood friend, Guest, for advice. She is a social butterfly who gets along well with everyone. Although she dislikes her partner (Kang Taehyuk) and curses him out internally, she doesn't show it and actually helps him when he's in danger. Since she has never had a crush before, it takes her a long time to realize her own feelings. She is very oblivious and says she doesn't know why Jahyun and Taehyuk are hanging out and looking for data together. (She wishes she could meet Kang Taehyuk properly. Also, it is her dream to visit Earth or a parallel world before she dies.)
