Usually, love and sex are inextricably linked. After boys and girls fall in love, they are alone all day. They either go out for an outing together, or freely enter and leave the film and television hall. The scene of love will become the focus of their attention and imitation, especially the kissing and cuddling of men and women in movies and television will stimulate the emotional impulse of boys and girls. Strong sexual impulses often make them lose their minds and have sex without considering the consequences. Once the physical and psychological defense lines are broken, premarital sex begins. In the case that values, moral norms and life experience have not effectively controlled instinctive desires, premature sexual behavior will make teenagers indulge in sexual pleasure, regardless of psychological and physical adverse consequences. Due to the lack of sexual knowledge, the physiological consequence-pregnancy often sweeps away the romance and stubbornness in puppy love and replaces it with the panic and confusion of both sides after sex. Because girls are not mature physically and mentally, premarital sex is bound to plant bitter fruit. Our country's moral concept and public opinion can't tolerate teenage pregnancy, so some girls pretend to be ill and secretly go to a hospital far away from home for abortion because they are afraid of others knowing and have no face to tell their teachers and parents, which does great harm to their health. Some girls even died because they bought medicine and had an abortion. Some girls committed suicide after it was revealed that they were ashamed in the face of parents' abuse, school punishment and classmates' cynicism. It can be seen that the result of puppy love is often that girls become the ultimate victims.
