for example, in chaos there's actually order... that is order of randomness and unexpectedness.
While in order, there actually seed of chaos which would sprout when a loophole was found or problem that caused a paradox occured .

From the 1st chapter....
I found it weird that a 'cure' that precious and valuable was put inside a inconspicuous bottle on a 'normal' desk by the doctor without any label or anything that indicating that it was a medicine...

Exactly! I also find it weird how he just drank some weird liquid he found on his employers desk without even a second thought.... unless he knew what it was and just wanted a excuse to fuck mc notice how he wasn't really surprised when the doctor said mc had to receive the medicine through intercourse??
that seedy and shady teacher are pretty childish... intentionally provoking Ren in a way that is so obvious. It was like he was getting some payback to someone who 'had it all' unlike himself
i think the teacher was in the same orphanage with him
