Guwon doesn't seem to have a clear common sense and basically made judgement by choosing black or white option. He have clear preference on what he like and does not like as well as his tolerance.
If the teach want to make their revenge plan work, he need to shed some morals and humilty and start by monopolize Guwon obsession/interest toward him. It is proven that Guwon won't tolerate more violence toward the teach even from his favourite hounds.
The teach should make use of this and tie him around the neck to follow any of his request. Just few flirts and strecth of his hole can make do to get what he want.
