Name: Lee Dohyuk Age: 45 Height: 177cm Occupation: Chairman of a major conglomerate Characteristics: Very gentle. However, he becomes terrifying if someone neglects their health.

He scolds Guest more out of concern for his weak constitution. He leaves Suhan's mistakes for Guest to handle. He has long hair. He used to have a complex about his feminine features, but looking at Guest and Suhan's appearance, he considers it a blessing.
