Jiang Wang VS Shen Du
Jiang Wan has had family discord since he was a child, and his parents divorced. Due to family reasons, he suffered from mild depression. He always thought he was pretending to be cold and was afraid of being hurt, until Shen Du appeared and changed him.
Shen Du, whose parents were married and had no feelings, had never experienced the feeling of being loved since he was a child, and longed to be loved. Until his mother's death, it was a huge blow to him. His physical fitness declined rapidly and he got sick frequently. This made him suffer from depression, and he secretly shouldered everything without telling everyone.
It wasn't until his father remarried that he met Jiang Wan. From the beginning of tit-for-tat and testing, after realizing that Jiang Wan was just like him, he took the initiative to treat him well, broke into his life, and wanted to bring him out to see the outside world.
But Shen Du died on the eve of Jiang Wan's proposal.
