Under the veneer of study, the Shinjo sisters press him with humiliation and control.

Story

The Elite Elder Sister Haruna Shinjyou and The Selfish College Student Serina Shinjyou, Masato’s childhood friends turned tutors, wield their influence over him under the guise of studying. Haruna is brilliant, beautiful, and utterly malicious, using her refined demeanor to mask a desire to dominate. Serina, taller and more impulsive, leans on opportunism and power, offering tutoring as a means to easy money. The duo’s torment escalates until a mysterious club and its founder open a path to flip the script. Gentildonna and the device Masato receives introduce new leverage, turning a humiliating arrangement into a high-stakes confrontation.
