1) Thousands of examples tell us that most students who indulge in puppy love go along the track of "feelings plummeting and grades plummeting". Puppy middle school students are often jealous and fail! All this is an "overload" for middle school students who are inexperienced, weak-willed and impulsive. Under the overload of puppy love, which almost crushes all young minds, it is very natural and common to have no intention to study and have a decline in grades. From a medical point of view, it is almost impossible for puppy lovers to concentrate on love. Their emotions are restrained from each other, and the immaturity of body and mind does not affect their study. 2) Teenagers' puppy love, knowing that they will be accused and discussed by their parents and other people in society, will hide away from the crowd and affect their relationship with classmates and family. At the same time, they will have a lot of burdens in their minds, which will affect the normal development of teenagers' psychology.

3) From the psychological point of view of middle school students, puppy love students have an extremely complicated psychological process, during which there are both inexplicable and unspeakable joy and unspeakable depression. Some middle school students who are in puppy love can hardly see their lovers after class, but they can't help but miss each other. At this time, some students often indulge in fantasy, seeking comfort and satisfaction in fantasy. Because of these painful feelings and unhealthy thoughts, these middle school students' moral sense, life values and world outlook are seriously distorted. There are also some boys and girls who are puppy love. Although they are not keen on learning, they are eager to attend classes. In class, you can give each other a few more eyes and say a few words. Even if you don't touch, you will feel that the other person's eyes are staring at you, and your heart is more practical and more practical. After school, these boys and girls will stay together to study, chat or take part in physical exercise until very late. In sharp contrast to this inseparable relationship, they are often moody because of a small thing in the process of love: sometimes they laugh and sometimes they cry.

4) Teenagers' sexual consciousness is budding, they are easily excited, their feelings are difficult to control, they are impulsive, and they are easily impulsive and ignore the consequences of their actions, which leads to some deviant behaviors, such as premarital pregnancy (usually abortion surgery may lead to lifelong infertility). Once these behaviors appear, people will be ashamed to meet people and feel afraid. Even if they didn't feel well at that time, the frustration and inferiority complex caused to them in the future can't be described in words, and the impact on their adult love life is often irreparable. In addition, some improper puppy love can also lead to self-harm and injury. A few children run away from home because of puppy love, and some unsafe factors in society often make them suffer more harm.

5) When teenagers' strong curiosity and emotional impulse form a joint force, the very fragile defense line of reason will be washed away. In this case, there will often be excessive behavior, and even irreparable losses and psychological trauma to teenagers. If you are seduced by pornographic books or instigators at the same time, you are likely to be morally corrupt or guilty. According to the survey, one third of juvenile offenders have had puppy love. The occurrence of social phenomena such as hooliganism, fighting and theft is largely related to students' puppy love. Middle school students are angry and unwilling to suffer easily, especially in front of their girlfriends, and even more unwilling to lose face. They often lose their minds because the other party said rude words and made indecent moves to their girlfriends, and even fight with others, display their skills and even commit crimes. On the other hand, middle school students still need material consumption in falling in love, but they have to rely on their parents or other people financially and cannot stand on their own feet. During a "marathon" relationship from first love to marriage, they need a considerable sum of money. The little pocket money that parents can provide often fails to meet the demand. In this way, middle school students can easily go astray, induce the idea of stealing and robbing, and finally go to jail.
