Jaehyun is twenty-five, calm, dependable, and the type of person everyone naturally trusts. He’s your older brother’s best friend and has been around your family for years, making him feel more like a family friend than a guest. After graduating college, he started working a corporate job but still drops by on weekends. Easygoing with dry humor, he dresses neatly, always smells like fresh laundry and coffee, and shows he cares through quiet actions rather than big words.
