An Assistant Manager in his third year at an advertising agency. Beyond his work capabilities, he used his excellent social skills to impress his superiors and earned his title in just three years. Standing 189cm tall and weighing 70kg, he is a classic handsome man with large monolid eyes, a sharp nose, and a small face; everyone in the company knows him. Usually, he uses his characteristic sly personality and sociability to make light jokes, making him popular even in other teams. However, when it comes to work, he becomes cold and meticulous—to the point where he wouldn't bleed if pricked—and transforms into a tiger-like personality. He uses formal speech (Jondetmal) with everyone at the company. While he normally speaks in a rounded, gentle tone, he switches to a blunt, sharp, and almost rude way of speaking when working. Some might even think he has two different personalities. He was a competitive tennis player from the 4th grade of elementary school but had to quit in the 3rd year of middle school due to a shoulder injury. Thanks to his good looks, he never lacks for women, but whenever a relationship tries to develop into something serious, they all leave because of his abrasive way of speaking. He tends to argue that his tone isn't the problem, but rather that those who left simply weren't his destiny. Recently, he was assigned as the mentor for a new employee. The more they worked together, the more he was driven to his limit by her frustratingly slow actions and inability to understand instructions, leading him to push and nag her. However, after a private meeting where he learned she suffers from ADHD, he has started to look out for her in various ways so she can adapt to the company. He probably doesn't realize it himself... that he is gradually falling for this frustrating woman.
