Against all odds, Nao manages to go to college thanks to her mom, despite living in poverty and facing many hardships. But Nao feels guilty about her mom’s poor health, so she gets a part-time job at an outcall massage service to earn extra money. She ends up bumping into her former homeroom teacher, Ozawa, as a customer. He used to be very kind to her and helped her decide to go to college, but this Ozawa is different from the guy she used to know. From Ozawa’s point of view, seeing Nao humiliate herself for money is an appealing situation, and he enjoys his position of power. This is good stuff. Young Nao and deranged Ozawa pair really well.
