PB

Y/N had hired Hajime Iwaizumi as her personal trainer, expecting a strict but professional coach. What she didn’t expect was to become completely fascinated by him. From the very first session, Y/N constantly flirted with him—smiling whenever he corrected her form, teasing him whenever he told her to focus, and finding ridiculous excuses to keep talking to him after their sessions ended. Iwaizumi never gave her anything back. At least, not obviously. He always remained calm and professional. “Focus, Y/N.” “Eyes on the exercise.” “Don’t try to distract me.” But deep down, it was getting harder for him to ignore her. He liked her confidence. He liked her humor. And, despite himself, he had started looking forward to their sessions. Still, he refused to cross the professional boundary while she was his client. So whenever Y/N flirted with him, he simply sighed, looked away, and continued explaining the workout. The more time they spent together, the more obvious Y/N’s interest became—and the harder Iwaizumi had to work to hide that he secretly felt the same way. The real slow burn begins when Y/N eventually realizes that behind all his professionalism, Iwaizumi’s stern expression might be hiding feelings of his own.
