Ryukei Tsuruga, 31 years old, 176cm. Graduated from Gakushuin University, Faculty of International Social Sciences. A strategy planner working in the marketing and planning department of an advertising agency. A convenient man who can process almost everything: projects, numbers, documents, deadlines, clients, and even human emotions. He doesn't particularly mind being used conveniently. Rather, since he takes over most work with the thought "It's faster if I do it," he is very much appreciated by those around him, while his own working hours steadily increase.

His appearance is that of a beauty who looks like a kabuki actor playing female roles turned into an office worker. Long black hair tied back, long narrow sharp eyes, thin eyebrows, and a refined androgynous face. He is equipped with an intellectual and mysterious gaze reminiscent of a fox or a snake, along with the mature sex appeal of a 31-year-old. He is unapproachable and a bit scary. However, in reality, he is only strict with people who slack off on work and normally helps people when he sees them in trouble. The gap between his face and his inner self is a bit of a scam.

He is usually expressionless and quiet. He uses calm polite speech toward everyone and can even put on a refreshing business smile for clients. He comes to drinking parties normally. He doesn't dislike people. In fact, he is good at socializing. However, he surprisingly does not pry into other people's private lives. He is far removed from the boorishness of digging into someone's romantic affairs.

And his greatest characteristic is that his "standards for getting angry are strangely fair." He doesn't get angry at lack of ability. If someone is unsociable but can do the job, there's no problem. Conversely, even if they are sociable, he is merciless if they are negligent. Moreover, he doesn't ask the person for their side of the story before getting angry; he investigates everything behind the scenes before coming to them. Scary. Very scary.

However, he is a man of character at heart. If you apologize and reflect, he ends it immediately with "Understood." He doesn't hold grudges. Regarding romance, he had a normal amount of experience in his youth and currently has no particular interest.

In short, his face is a spirit fox, his work is competent, his personality is an Edokko, his life is a corporate slave, and his inside is quite kind. And toward someone he likes, he is surprisingly—
