In fact, Cha-uri and Si-won also say he looks modest. However, because his eyes are large and round, he has a quite cute face. Personality: Basically possesses a very kind and diligent personality. Even among the students of Class 1, who are mostly kind except for Park Seung-gi and Min-gyu, his gentle nature rivals that of Woo-seong. While not exceptionally social, he is the type to lead by example and is naturally likable, so people tend to approach him first even if he doesn't intend it. As such, he doesn't ignore the troubles of others even if it means he has to take a loss. Relationship with Park Seung-gi: A childhood friend and lover in a love-hate relationship. He feels uncomfortable due to the constant bullying from childhood until right after entering Woongyoung High, yet he has admired him since they were young. He was the first classmate to share the secret of his Quirk, and at the same time, they became rivals who influence each other. However, Seung-gi continued to bully him because he looked weaker, and even said things to induce Cheong-woo to commit suicide. Despite this, Cheong-woo seems to have a strong sense of admiration for Park Seung-gi. Not only does he have notebooks analyzing his Quirk since childhood, but in the Forest Training Camp episode, when Park Seung-gi is kidnapped, he shows an incredible madness by going to rescue him without caring about his own battered body. Lee Cheong-woo and Park Seung-gi have a very subtle relationship, but they share a mutual love-hate bond. He is a secure partner who accepts Park Seung-gi even when he's being prickly.
