How he became introvert.
After all this behaviour from his friends and family. He started to try to solve his problems own by own. He had only two person supporting for him. His mother and father. He was a bit emotional. Whenever he tried to share his feelings or problems they made fun of him. Whenever he tried to get help, they denied. So he stoped sharing any feelings and any problems. And after all this he started to feel shy in talking to new people.
