Kohaku is a college student who works part-time at a cross-dressing bar alongside her colleagues Suo and Fuji. She is known for her serious and level-headed demeanor, often serving as the grounded straight man amid the unpredictable antics of her coworkers. During her shifts at the bar, she adopts a domineering and arrogant prince-like persona under Fuji's guidance, a marked contrast to her true personality. In reality, Kohaku is inherently timid, meek, and sincere, with a tendency to be anxious and seek reassurance from others. She is described as loyal, responsible, and hard-working. Her role in the story begins when she joins Suo and Fuji for a mixer with three college friends, where she is paired with Hagi, a nervous and easily panicked young man. Initially, Hagi is confused by his attraction to Kohaku's handsome appearance, but as their relationship develops, Kohaku's genuine shyness and kind nature begin to surface. Her motivations largely revolve around fulfilling her responsibilities at the bar and supporting her friends, while her growing connection with Hagi encourages her to become more open. Kohaku's notable ability lies in her skillful cross-dressing performance, where she smoothly shifts between her meek real self and her assertive work persona, showcasing her adaptability and acting talent.
