Ishigami, who works for a major advertising agency, is dating Ruisa, who works as a receptionist at the same company. However, Ishigami, who is in love with Luisa, is frustrated every day with Luisa who refuses to let her live even though she is engaged. One day, the company's boss and seniors invite "Ruisa" to preview a comfort trip, but... A perverted NTR propensity that awakens in a hot spring inn and a thick circle that is repeated in a cloudy bathtub stained with semen crossover. #Yoro P
