In my opinion, most boys who have a good relationship with most girls in the class are people who have a certain position in the class. First of all, boys who have a certain position in the class must be proactive in making friends and have an optimistic and lively personality. Only in this way will they be willing to deal with the same sex or the opposite sex. Secondly, only class cadres can have more opportunities and needs to contact all the girls in the class. Even lively boys have something in common with most girls in the class.
As far as I'm concerned, my college monitor has a good relationship with most girls in the class. Because of his position, he needs to contact many girls in his class from time to time. At the same time, he is lively and cheerful, and is willing to deal with people. If he needs it, he will help anyone in the class. So under such circumstances, he has a good relationship with most girls in the class, and even the girls in the class call him by his nickname when they meet. This is also the best example of the length of a class.
