Jihwa knows nothing

Jihwa believes that he knows Seungho more than anyone else. However, everything he does seems to be the acts of someone who doesn't know Seungho at all.
Jihwa should know better than anyone that Seungho has big trusting issues. Betrayal is something he can't forgive. However, deception and manipulation is what Jihwa keeps trying with Seungho.

Look at all the ways Jihwa showed Seungho that he can't trust him:
- He placed a spy servant inside Seungho's house;
- He sabotaged Nakyum's painting so Seungho would think it was NK doing it and punish the lowborn.
Even if Seungho didn't care a bit about NK, I bet that the fact that Jihwa tried to manipulate him into doing something would already piss him off.

- He uses something he knows from Seungho's past to lure Seungho to meet him.

This is of course besides the biggest betrayal of all: to hire an assassin to eliminate Nakyum, a lowborn that he could actually kill it in public if he wanted and get away with it. The only reason he is doing it in secret is exactly because this hit means betraying Seungho, again, and he knows it.

So Jihwa is actually a contradiction of his own. He is indeed the person that should know Seungho the most .... but instead of using this to his advantage, he keeps doing everything that Seungho hates the most: being a fake and stabbing him in the back. Even if Jihwa thinks this is justifiable because of his feelings, from Seugho's pov, Jihwa keeps showing he will lie and do anything to manipulate him.
