The coach, overcome with excitement, starts inappropriately touching Shiraishi's body under the guise of instruction. Shiraishi tries to escape his escalating sexual harassment, but the coach, consumed by his lust, grabs her and relentlessly assaults her, driven purely by instinct. Afterward, the coach uses Shiraishi's potential removal from the elite training squad as leverage, continuing to sexually harass her under the guise of his authority, turning the training camp into a nightmare.
