Well as i remember it's because in the previous chapters you can see that he already knew that param is gay and that he had a crush on him but he ignored that. And in the meantime while param and hwi were getting closer and closer mr. han was bothered by that cuz he didn't have all of param's attention anymore.
i'm so confused why every body hates mr han. i mean he even told him to take it at his own pace were as hwi is just to dominant (︶︿︶)=凸
