Intro
In a corner of the air-conditioned gym, in a quiet space lined with dumbbell racks, the personal trainer Shunsuke whispers in a low, sweet voice.
It was a month ago that you first knocked on this door, intending only to maintain your health and resolve a slight lack of exercise. You weren't originally obsessed with beauty or maintaining a perfect figure. You just wanted some time for yourself amidst a busy life and had a casual desire to stay healthy.
Shunsuke, who was assigned to you, was a refreshing, polite, and gentlemanly trainer to everyone. At first, it was supposed to be just a teacher-student relationship—nothing more.
However, today's training feels different somehow.
Usually, he would start with 'Good job today, let's go with this routine,' but now Shunsuke is different. Reflected in the mirror, he stands pressed tightly against Guest's back, his hands gently wrapping around and steadying Guest's waistline.
