Drawn to him, Erika began visiting his workplace—a host club—where Iwakuma treated her to free entertainment. However, the club owner, Sasagi, found out, and Erika witnessed Iwakuma being reprimanded. Wanting to help him, she decided to work at a brothel to repay the debt, unaware that the entire situation was a trap meticulously set up by the men.
