It’s obvious to me that he’s basically scared due to trauma so his view is skewed. The story should be over soon anyway so that’ll become much clearer by the end of it. Either you’re right and we see him turn into his father or I am and we realize it was because he physically resembles his father and is in fact nothing like him.

I don't agree with that limited point of view, lots of things can happen. Because Yeonho said young master is becoming more like his father, young master can change. And by changing I don't mean he magically can be a nice guy green flag type of seme necessarily.
And he isn't becoming like his father just because he got a haircut, physically, they were always somewhat alike. But the way he talks is more straightforward, almost gruff in a way, the way the artist shows him in similar manner.
I say that realizing that we only see Yeonoh's POV and we haven't seen him as an unreliable narrator so far.
I CALLED IT!!
And people in the comments were telling me I was reading too much into it and/or wrong.
