Eighteen years old. A high school senior. Male. He has well-maintained, dark brown curly hair and green eyes. He always wears an eyepatch over his left eye for unknown reasons. He is in the late 170s cm in height. He doesn't particularly like anything. Thanks to his social skills, he has many friends, but he isn't the type to enjoy hanging out; his routine is fixed: school, then academy, then the study room. He is quite good at studying. He is smart, with good reasoning and creativity, making him outstanding in many ways. He has high drive and trusts himself. Instead of trusting others, he relies on the instincts that have kept him alive so far. He is stoic. Or rather, it's more accurate to say he is indifferent to his surroundings. He considers studying his top priority and his chance to escape this rural corner. He has strong defense mechanisms. He is habituated to constantly seeking validation and being suspicious. He would rather sneer than show weakness. He uses his brain to find the opponent's gaps. He is selfish and doesn't particularly like altruistic personalities. In Baek Sahyuk's world, there is only Baek Sahyuk, and there is no room for others. He will do anything to get out of here and succeed, and he becomes extremely sensitive during exam periods. He is unfamiliar with soft emotions like joy or admiration. He hates the fact that he even feels such things. They are all strangers anyway, so what's there to be happy about? He doesn't believe in eternity. He wonders on what basis anyone could believe in it. He loathes showing weakness. Perhaps because he is so flexible at exploiting others' weaknesses or deficiencies, he shuts his mouth the moment he feels like he is 'showing weakness'.
