The new transfer student Xu Biyuan is good-looking, but he is also a college bully and the school bully Su He Xuchao has a sense of CP.
Xu Biyuan: Good roommate, withdrawn personality. His parents divorced and he followed his mother. Not long after the divorce, his father was forced to commit suicide by his creditors. Xu Biyuan was eight years old. The sun was so bright and hot that summer, but his world was dark and cold like winter. Fortunately, his parents divorced and his father took away all the debts and paid them off before he died. The mother was a strong woman and the life of mother and son was pretty good, but he was a little autistic and never dared to talk to anyone except Su Hexu.
Su Hexu: The eldest young master, the second generation of rich people. He grew up in a good family environment and he looks good. He can play and talk to whomever he wants. He is too lazy to take the initiative to ignore Xu Biyuan if he doesn't talk to him.
Intention: That beam of light illuminates the rest of a lonely boy's life. Because of that beam of light, the boy's world becomes brighter for the rest of his life.
