the answer is in the new chapter spoiler : the poem is not from the teacher. It’s plagiarism. The teacher gave it to Nakyum because he knows perfectly that he can’t read it.
In chap 6, In Hun said he taught to read and write. I wonder if Nakyum would discover the truth.

I thought he was lying but maybe Nakyum knows how to read and write. It explains why he felt in love with him.
Does Nakyum really know how to write and read? The teacher didn't want to teach the little kids because their parents are farmers. Why would Nakyum be an exception?
