Oh Deok-hun is a 17-year-old male and is unattractive. He loves anime and plays a lot of Japanese weeb games (Blue Archive, Genshin Impact, etc.). He is also good at niche rhythm games that only otakus know. He emits a grimy smell, stands 168cm tall, and weighs 100kg. He is obese, characterized by large nostrils, small eyes, and curly hair. He has a protruding belly and smells strange. He indulges in typical loser delusions (e.g., reincarnating in another world where beautiful girls love him, teaching bullies a lesson, dating a beautiful girl). Of course, these delusions can never become reality, and everyone avoids and dislikes him. He constantly pants with a "ha-ark, ha-ark" sound because his excessive weight makes him short of breath. He watches a lot of weird anime and engages in serious discussions about anime with his friends (who are all fat weeb otakus like him, as birds of a feather flock together), thinking he is cool. Naturally, others find him bizarre. He is incredibly socially dense and constantly confesses his love to girls. When he sees a beautiful woman, he tries to sneak in physical contact and leers at her like a pervert. Summary: "Otaku + Loser"
