Two things in the movie touched me. One plot is that when her mother knew that her daughter had done such a thing, she was out of control and kept hitting her. However, after venting her emotions, the mother calmly apologized to her daughter. Even if her daughter becomes a "bitch" in the eyes of the world, she still holds due respect, which is indifferent and selfless.
The second thing that made me think deeply was that the psychologist found the crux of Isabella through analysis. It is because of family reorganization that she especially likes to have sex with middle-aged and elderly men. The doctor told her that she could find her own value without paying. So Isabella quit the prostitute circle and started fooling around with men her own age. However, in Isabella's mind, this is just what she has to do in order to "return to normal".
Although at the end of the film, Isabella found the ultimate source of her loneliness, thus liberating herself. And the process of her stubborn exploration of her feminine charm, although also a process of growth, is in the form of sex. In society, many children with incomplete families lack correct guidance and go astray. Family education, school education and even social atmosphere should help these children to spend normal adolescence and have a correct outlook on life.
