Raped by an Angel 5: Advertising Temptations(2003)

Overview:

Lung is in his twenties, thin and silent. No-one notices that he is psychologically deviant. He is obsessed with three female advertisement models: Judy, from a wedding ad, Pauline, presenting shower gel, and Yen, an advertising girl for soda. He imagines that the women will surrender to him one day, but in reality he is just an average person.
