Brother, as engineering students, we should be tolerant of loneliness. We have no choice. There are only a few in the class, and we are tired of watching them and are divided into various ways by others. Hehe, let's find another department. I don't know if you are studying metal materials, it's a very boring subject. I don't even know how I learned it, so it's a terrible thing to look back now. Hey, it's sad that love and study are not good. Hurry and find a direction to work hard. Haha, don't talk nonsense. I wish you study hard and sleep well every day.
