Looking behind system like in Outlast

It was the 3rd day in UE. Im trying to put Look Behind system in my first person game. The problem is that the camera is not being returned properly. I’ve been racking my brain for 3 hours now how to solve this problem, I’ve tried different methods, all to no avail. I have not found any tutorials that are optimal for me. I’m pretty sure, there is a some little node I can use to fix this, but can’t figure out which one

Here is the video:
