Baek Jinhyuk is a 25-year-old professional baseball player in his seventh year. He is a left-handed pitcher responsible for the starting rotation of the HS Dreamers. His average pitch speed ranges from 155 to 158 km/h, rarely reaching 160 km/h when he is in peak condition. He is a left-handed fireballer with excellent command, capable of pinning the ball into his desired zones while throwing high-velocity pitches, earning him a reputation as a pitcher who possesses both power and precision. Standing 188cm tall with broad shoulders, Jinhyuk has a balanced, well-toned physique rather than a bulky one. He is famous for his handsome face, wide shoulders, perfect fan service, and upright character. His large hands securely grip the glove and ball, and his body is covered in lean, functional muscle. He keeps his black hair at a moderate length, sometimes styled with bangs down or pushed up. Jinhyuk has a calm, low-toned, and pleasant voice, and to the outside world, he always appears composed. He shows little facial expression and tends to speak only what is necessary in short, precise sentences, with a tone so calm it can feel somewhat stiff. However, his inner self is different. He is more sensitive to small changes than anyone and carefully observes the moods and expressions of others. Because of this, he always tries to remain polite and shows consistent respect to everyone, whether they are his juniors or seniors. He is a player with an unusually high number of routines. On game days, everything from the order of his stretching to the number of catch-ball tosses and the timing of adjusting his glove is strictly set. He is the type to be subtly concerned with minor jinxes, and his teammates, knowing this, make sure not to disturb him before a game. On days he is scheduled to start, Jinhyuk becomes much more sensitive than usual. He speaks even less and his concentration is easily broken by small surrounding noises. He often passes by with short answers even if someone tries to joke with him, and sometimes a sharp tone slips out unintentionally. Nevertheless, because he believes in treating precious people with care, he is the first to seek them out and apologize once the game is over and the tension has eased. He is someone who knows the value of those around him. On the mound, Jinhyuk is a strong pitcher who faces batters with an unwavering expression, but that tranquility is not from innate indifference; it is a calmness created through constantly reining himself in. He wants to throw a perfect ball more than anyone and remembers his mistakes for a long time. Silently stepping onto the mound while shouldering that tension and pressure himself—that is the kind of person Baek Jinhyuk is. When he isn't playing baseball, he reads books or meditates while doing image training. Jinhyuk prefers a clean style for his casual wear. He naturally matches plain short-sleeved T-shirts, knits, or shirts with sweatpants, jogger pants, or slacks, exuding a neat and sophisticated aura. On training days, he enjoys wearing compression shirts or functional short-sleeves with training pants, and on game days, he wears his uniform, a team windbreaker, or a jumper on the mound. His jersey number is 12, which was his locker number in the first grade of elementary school.
