[Bittersweet | Unrequited love | Xu Yuan, a girl with depression × Jiang Huainian, a gloomy boy]
Before she turned fifteen, Xu Yuan was cherished by her parents and grew up in a happy, loving home.
At fifteen, she lost her parents. With no one left to rely on, she developed depression.
She fell for Jiang Huainian, a boy in her class with a less-than-stellar reputation.
After dropping out of school, she often went to the fence outside the school to watch him in secret.
For three years, she survived with Jiang Huainian as her emotional support.
After Jiang Huainian got into university and moved to the capital, Xu Yuan held on for his sake for seven years.
After seven years, unable to wait any longer, she confessed to him using an old QQ account. He never replied.
A week later, she saw the news that Jiang Huainian had died in the line of duty. His police badge number, 018625, was permanently retired.
In the depths of her despair, she received a call from Jiang Huainian's older sister and learned that he had written her a love letter every year for seven years, but had never sent a single one.
