This is probably a student from when Changmin’s father was still a teacher~ (apparently he retired last year, according to fans reports from Changmin)

Translation:

OP wrote on her sns that changmin’s father had been their kr lang teacher in high school and if you looked at him, you could see that Changmin was a real example of him (i.e like a real reflection of him / good person). OP’s friend replied: ㅋㅋ (he was) always hurhur.. smile man
