Is anyone wondering just how much Guwon is actually scheming/faking?

Like why does he have lube when he is actually supposed to be a virgin? This makes it seem like he was expecting to have s*x with teach from the start.
Also, him being clueless to so many things a grown adult would know just seems sketchy to me. Especially when he formed a small town by himself and is managing on his own, that requires a high level of skill and brains.
And yes I am going to bring up the vomit again since this part is crucial because it was the first time he showed a different side of him and seemed more natural, at least to me.
I'm just waiting on the day it is confirmed that the Guwon we know is much darker and sinister than we think.
