ok, I don't know if anyone will be able to answer this, but I have a question about chapte...

It seems like he finally figured out that SH cares about Nakyum for real... which gives him the opportunity to further manipulate NK if he needs to eventually.

Till now I think he never really realized how SH was being so obsessed with NK. Inhun say to himself 'till the very end he (seungho) always mentioned nakyum whatever I said.' Then he visualized the times he saw them together and connected the dots, nk= sh's weak point. Then he also says 'it seems like he(nakyum) still can be useful.' And left,, so it seems like he will still try to manipulate Nakyum in the future.

But here again he fails to realize that BNK has no longer any admiration for him. BNK won't contact him any more. Asking to throw the painting away shows that BNK doesn't care any more for him.
But Seungho is not stupid like this learned sir... he is well aware that BNK has become his weakness. If not, why would he have a servant following BNK, while he is alone all this time... Notice that BNK was sent to the tailor with his loyal servant and Seungho arrived much later alone. Jihwa and In Hun are not aware that BNK is no longer alone but he has someone by his side.

I think NK is far from being done with his love for his teacher. If it was the case, he wouldn't stand there waiting for him to give him his drawing and say good bye (and probably good luck as well). His last discussion with In Hun made him feel worthless of his love. He blames only himself and never reconsidered his teacher's intentions. He threw himself in SH arms as a self-punishment. He is still craving for the learned sir attention and respect. Even SH is aware of that. He actually cares so much about NK that he even asked In Hun if he will say good bye to NK before leaving. To what the teacher replied: "Is it necessary?". SH also managed to send him away quickly for his exam because he knows NK's mood is still influenced by his teacher. He wants to get rid of him and finally gain NK's attention.

wow, these answers are so much more constructive than I thought they would be. thanks everyone! keep up the good work and keep up those theories! this story has so much to dissect, it's amazing :)

Yes, he waited but in the end, he decided to throw away the painting and this marks a turning point for BNK. Someone wrote that BNK added that In Hun wouldn't have appreciated the painting. All this shows that BNK has given up on In Hun. On the other hand, In Hun might have even forgotten what he told BNK... since he is a low-born and prostitute, why should he pay attention to BNK's feelings? So in my opinion, In Hun will try to reconnect with BNK in order to get more support.
The question is: will In Hun succeed with the examination? It would be interesting if he failed...

Oh you made a good point there, I didn't even think about that. Well I'm just way more excited for the next season now !

I globally agree with that but I think NK wanted to give this painting to IH to like finally let those feelings go, the servant even said something like 'it seems you put a lot of feelings in this one' but seeing that he(inhun) already left, nakyum just asked the servant to throw it away anyway. When he made eye contact with seungho we can see that he's no longer afraid or embarrassed, I truly do think that he's trying slowly to move on, but obviously those strong feelings he had for inhun won't vanish this easily.

When he was waiting for In Hun, he no longer showed any excitement. He was quite passive compared to the time, when he heard about In Hun's arrival and almost jumped into his arms. Notice the contrast between the arrival and the departure of In Hun... BNK was not smiling, he just wanted to give him a painting as a sign of respect, since the ex-teacher is a noble. But that was it. BNK never came looking for him.
Furthermore, it looks like In Hun left the mansion through a different door (the entrance for the nobles), while it looks to me that BNk was waiting at the entrance for the low-born and servants. So In Hun never came to his side confirming what In Hun had told him previously. He never showed any care and respect for him.
To me, In Hun is always one step too late and too emotional in reality. Even Seungho is not really expecting him to succeed. The deal was proposed because of BNK, since the latter remains by his side now and is painting, Seungho no longer cares for In Hun.
