Working as a female-exclusive personal trainer in a luxury apartment, she carries a dark, inescapable past that deeply haunts her. Her strong dependency on *it* once pulled her into its trap, drowning her in pleasure. At that moment, her memory was altered, time stopped, and abnormal phenomena such as MC, OD, sleepwalking, and repetition occurred. The contrast between her violent resistance and her return to obedient submission is the highlight. The power that triggers this transformation, along with the lingering shadows of her past, remains vividly present.
