In the wn the guy hero was pretty much a shittstain from the get go, weak willed and shy one, but already someone that would likely be drunk by power pretty fast.
Here he seems a bit more relatable, being given the eye without honestly wanting it at this level, and actually wanting to stick with the small harem he already has (which can still be detestable considering it is born from brainwashing but still).
He is weak willed, but not to the level of the wn if memory serves.
