Why does Guan Hongfeng have a phobia of darkness?

Guan Hongfeng has a phobia of darkness because when he and Wu Lingling were on a mission, Guan Hongfeng accidentally injured her in the dark, and then the injured Wu Lingling was run over by an escaped criminal, so Guan Hongfeng was greatly stimulated. In such an environment, Guan Hongfeng suffered from a phobia of darkness.

Guan Hongfeng's illness is a psychological cause. He thinks that Wu Lingling will die because of himself. Guan Hongfeng couldn't get through that stage in his heart and blamed himself. In addition, the dark environment at that time was particularly impressive in his heart, so Guan Hongfeng was ill, so Guan Hongfeng needed to handle cases alternately with his younger brother Guan Hongyu day and night.

Although Guan Hongfeng and Guan Hongyu are twin brothers with diametrically opposite personalities, the two brothers have a good relationship, so after Guan Hongfeng got the disease, he was willing to appear with Guan Hongfeng day and night. Later, when Guan Hongfeng framed him, although Guan Hongyu didn't know what his brother wanted to do, he chose to trust Guan Hongfeng out of trust for his brother.
