Yuna, who usually works as an OL at a travel agency, was more timid than others and was nervous about trifles at work. One day, when she is in the bathroom at work, the emergency bell suddenly rings. Not knowing that it was her evacuation drill, Yuna jumps out without panties in fear. When she finds out that she is wearing no panties, her staff mistakenly believe that Yuna is seducing her, and she is raped. And even in the first aid training that was held at a later date, the members groped Yuna's body under the name of her guidance.
