Perhaps the casual, backward, and irresponsible attitude towards work is the reason why the beautiful department head Yua decided to send the employee Kusanagi to sign a contract with their partner with the hope that he could further develop himself. After successfully signing the contract, despite making a few minor mistakes, the department head arranged for him to find and book two hotel rooms for the night. This time, he was late again and could only book one room, circumstances led them to share a room that night with some bottles of wine bought to drink at her request. With a bit of alcohol in her system, she began using stimulating words to point out his mistakes in the sales process with the intention of helping him learn and grow. But she did not anticipate that her misguided guidance filled with her own sensitive words would only make him more frustrated, aroused, and ignite the flames of desire within him, leading to a heavy consequence that she would have to bear.
