IKR? Yet he has the nerves to still make fun of the boy and mock him whenever he wants about how illiterate he is.
You are his teacher, man, it's your JOB to teach him and provide him basic knowledges.
If he's still illiterate at this age and day then it's your fault.
Though it's not surprising at all, if we remember how he thinks about the kids of the village that he was tasked to teach but doing nothing and just let them run in the dirt and hill, because for him it's useless for peasant children to know how to read. Nakyum isn't different from the rest of these kids for him.
Furthemore, he hates this job and thinks he deserves a much much greater position. And we know how he got to enter the Yoon household, thanks to the blind admiration of our orphan for him.
The dude is looking down on everyone except himself, is not even a teacher and that's why readers hate him, it's not only because he's fake or abuses mentally Nakyum.
Yes, it'll be nice to see Seungho teach reading to the boy, that will be a refreshing change for the story, and maybe Nakyum will start to see how a real teacher should be (crossed fingers).
At first I thought that Inhun had at least served the purpose of teaching Nakyum how to read ... but apparently not even that he managed. What a lame teacher. Nakyum apparently is still as illiterate as before. The only thing Inhun taught him was to be ashamed of his desires (that he expressed by painting male erotica).
It would be sweet if the next thing Seungho does is to start teaching Nakyum how to read or find him a tutor.
