My Teacher Is Not Much of a Teacher

Although he is a retired mercenary, his dream has always been to become a qualified people's teacher. Although he seems to be carefree, drinking, smoking and fighting, he gives the students the most sincere care with all his heart. Although he sometimes couldn't answer students' academic questions, he did his best to teach students all the principles of life and work. Although he took over a devilish class that no one else took over, he successfully brought this class to the other side of victory. He may not look like a teacher, but he is the best teacher in the eyes of students!
