There may be more later on, but at least in Episode 1 it is seemingly Lin Ling's feelings for Moon that let him overcome Fear, but the scene in Episode 1 can definitely be looked at in a different context now since I think that scene was showing how he did get a dose of fear and that fear was trying to mess with his brain which is why he went right back to the moment where he wanted to kill himself.
This also may be why Moon had to go because probably one of the CEOs connected the dots because all of the CEOs had their eyes on Lin Ling after episode 4.
