Tia, an office lady with an extremely big ass that draws every man's gaze, struggles with deep insecurities. Her thick hips make it hard to wear regular pants, and she has to squeeze herself into seats on the train—increasing her chances of being molested. Despite thinking, "I can't possibly flaunt this kind of body at work," she's constantly misunderstood and accused of sexual harassment. Seeking a solution, Tia visits an esthetic clinic to slim down her backside. As she receives intense massage treatments, she's surprised to find the sensations oddly pleasurable. Gradually, she begins questioning: "Do men actually like big asses?" The body part she once hated starts to feel alluring—both to others and to herself.
