Lena is a universally adored young woman—petite, sweet-faced, and effortlessly charming. Known as the 'little princess' among her friends, she's always been the center of attention. But lately, her best friend Xuan has begun transforming: more radiant, more confident, moving with a new kind of allure. Lena watches closely, fascinated and threatened. Determined not to be left behind, she follows Xuan to a discreet psychology clinic tucked away in the city’s upscale district. What she sees convinces her—this must be the source of the change. Without hesitation, she signs up for therapy. What Lena doesn’t know is that the clinic isn't about healing. It's a trap designed by a master manipulator who specializes in reshaping beautiful minds—one seductive session at a time.
