In Jiangzhou in 2018, the life of Lin Ye, a high school sophomore, was split in two. At school, he was an “invisible person,” deliberately hiding his talents, with an old scar concealed beneath his white shirt on his left wrist. Deep in the old alleys, he was the only son of Lin Zhengxiong, a gang leader, unwillingly drawn into a vortex of a torched delivery depot and betrayal from within. The class monitor Su Wan’s kindness shattered his disguise; Chen Nian, the daughter of his enemy, tested him and found an unexpected kinship; while the quiet companionship of his neighbor Xia Zhi concealed ties between their fathers. As the police investigation closed in and the gang feud escalated, Lin Ye stood at a crossroads between “running away” and “taking responsibility.” He had to protect the innocence of campus life while carving out a “clean” path for himself on the edge of darkness. And the girls who entered his life would eventually learn to make their own choices alongside him, through the growing pains of youth.
