He used the MC (Tan feiyang) and mc's brother (feiyu) for his revenge. He also hide the any info of MC (mingyi) from MC (feiyang), as well as his feelings for mingyi. He (ML) made his half brother drug addict. Yet all the younger brother did is just to humiliate the ML verbally and talked bad to ML's mother. This led the ML's mother to die. But the main culprit is the ML since he went to his father, and his father since he didn't help the ML's mother. Now, I understand why tang feiyu is against the ML.

I just pity Lin qihang. His role looks like one of the MC in counterattack of cannon fodder. His mother from Zhao family was only used by his father Lin Zhengping to climb the ladder. He was eventually became drug addict due to ML (bought the actress to let Lin qihang took drugs and became addicted). Though the ML warned him to stop taking drugs, qihang is already addicted. Then Lin qihang made revenge through the MC via car accident. And Lin qihang was sent to jail for 6yrs. And Now the ML will retaliate to Zhao mu.

The typical scene where the MC kept being delayed to tell to his fifth brother that he is mingyi. The MC also didn't even bothered to first find the reason why his wu ge is still an 18th line actor, given how many resources he has. And the MC's reason is that he respected ML's privacy and wanted to know the truth from ML itself. Yet the ML didn't want to disclose. Hasn't the ML think that the MC will eventually know the villain if he shows himself? At least they are prepared. Eventually the ML divulged his past. The author just wanted to prolong the story ?
