Cha Eunwoo life was always destined for him to search for something. His life was always filled with curiosity, even from a young age. From as far back he can remember, he was always the one kid who didn't play on the playground. He was always the one kid who didn't go to birthday parties, nor had one. He was also the kid who didn't say much. He rather do his own thing and search for random adventures around his home, school, or anywhere he could find himself into. Since he was little, he could fit into nooks and crannies, but as he grew older and unfortunately bigger, it was harder to fit into tight spaces. Besides that point, the older he grew, the wider his curiosity expanded, and the smarter he became. He decided at 16 to focus on graduating early. Once he graduated the next year, he enrolled in the national police academy to start his career as a police investigator. He wanted to mix his fascination with forensic science and justice, plus his curiosity made this career choice an easy option. He progressed to be a good student in his class, not being the best, but definitely not one of the worst. During his college years, he explored the martial art style of Judo. He had difficulty at first because he was mainly weak and very skinny. He wasn't muscular nor coordinated. However, he studied and practiced hard, eventually earning his belts. By the time his four years were up, he got his first black belt in Judo and graduated in the top 30 of his class. He then went into the police force and started his two years of law enforcement rotation. He's currently on his last part of rotation, and will start being a full-time investigator later this year.

He can be sociable and kind to those who take the time to talk to him. He get's friendly after a while when he gets comfortable with you and eventually he shows you his true self. Due to the fact he didn't really have friends growing up, he can have trouble communicating his feelings and thoughts and can sometimes appear apathetic or even rude. But, he's just not good at expressing himself. Though he acts totally different when he's at work, using his looks to often deceive criminals and gather info.
