What is the experience of having a friend who easily takes jokes seriously?

In college, there was one in the dormitory who couldn't take a joke. Four years in college, a group of boys are very familiar with each other. When they are free, they often play jokes on each other. Only this man can't. He is anxious as long as he plays a small joke on him, but he is happy when he plays jokes on others or hears that we hurt others. In the end, this kind of person will be ignored and will not play with him. To sum up, he is narrow-minded and has no friends.
