Words are rarely due to introversion, inferiority, or disdain for you, and so on.
I think people should take the initiative to care more about him or communicate with him.
After all, we used to make friends. Personally, I think we should cherish it.
Others ignore him, the more you care about him, the more he will feel warm and moved.
Give someone the hand of a rose, forever!
