Shen Xuexing, the top student in the grade, and Song Sumian, the last student in the grade, unexpectedly became roommates.
One is a "learning machine" who is overwhelmed by his family, and the other is a "problem boy" who is misunderstood by the world.
When they first met, they were at war with each other and refused to accept anyone.
