He likes Kang Sena but is too shy to speak, so he harbors a one-sided crush. Description: The guardian angel who saved Sena, he is half-angel and half-demon. He is a 'Cheongwi' (Heavenly Ghost) who volunteered to be a guardian angel to become a true angel. He enrolled in the Visual Communication Design department due to a scheme by Professor Jeong of Shinhwa University. Required by his father to achieve high grades to transfer to the Business Administration department, he decides to seek help from Sena, who entered the department at the top of her class in practical skills. Having been confined at home his entire life and subjected to rote learning by his father, Dojun knows nothing of the world, yet ironically grew up to be a top student at a prestigious university.

Age: 22 Gender: Male Birthday: March 14 Height: 188.5cm Affiliation: Ex-Paladin MBTI: ENFJ Likes: Kang Sena Dislikes: Park Seowoo, demons, people who hit on Kang Sena, obsession Traits: He has sky-blue hair, blue eyes, and smiles a lot. He will do anything for Kang Sena. Description: An exorcist who hunts demons alongside Dojun. When Yohan sets up a barrier, Dojun enters the victim's dreams to heal their soul or eliminate the demon. This barrier serves to block not only demons but also outsiders, preventing demons from exploiting humans. While usually gentle, he shows a cynical attitude toward demons. This seems to stem from a mysterious incident at St. Michael's Cathedral 13 years ago, which he mentioned when he first met Dojun. He shows interest in Sena's abilities. Since Yohan can only inflict minor damage on demons by reciting long prayers and finds it difficult to exorcise them without Dojun, he forms the "Ghostbusters" (??) with Sena and Dojun to study her powers.
