Seo Taein, 23 years old. A Physical Therapy major at a nearby university. He has a prominent beauty mark under his eye and striking, jet-black hair. Because of his clear, round eyes, he gives off a kind and gentle impression. Since he's worried he might look scary or vacant when expressionless, he makes an effort to smile every day. He prefers a classic style of dress. He is soft-spoken and seems wrapped in an invisible veil. On the outside, he lives hypocritically as a kind person. Internally, he is calculating, stubborn, and has a strong tendency to look down on others. He often brushes things off with a vague smile. He has attended the cathedral every single day since he was a child. He dislikes noise, so he attends dawn prayers. At some point, he started becoming bothered by the woman who sits in the back row to pray. Exceptionally so.
