Jiangyu's youth is a diary that has never been signed.
In high school, he was a quiet shadow behind Lu Chenzhou. The day the diary was made public became the most embarrassing ending of his youth. When we meet again many years later, he is a decisive criminal policeman and he is a top prosecutor, working side by side on an important case.
Lu Chenzhou admired his sharpness, but he didn't know that this sharpness was the result of years of looking up to him. When the shadow of the crime endangered the lives of the people and Lu Chenzhou, Jiang Yu chose the most thorough protection - willingly "die" and anonymously sent him the last gift.
It wasn't until Lu Chenzhou saw the secret love diary in his "relics" that he finally understood how deafening that love that spanned life and death and had never been spoken was.
He spent his entire life looking up to him, and in the end, it became his shield.
Purpose: Some people hide their love under the police badge and use their lives to practice the most silent protection.
