dude, i'm reading this for the first time and i just got to that part. like bruh what the hell man. like i'm assuming there's a reason he behaved like that but the poor uke
You see later that the owner of the necklace is like a parent to him, he is still a child himself, just in an adult body. The whistle was really important to him, he acts on emotions like a child and he hadn't quite built much emotions for Mohkwa, he gets really cute later.
Well, if you think he's an animal it makes sense. When they are annoyed or don't want others to do something, they usually scratch, bite or growl. It depends on the animal
I'm glad that changgyeong and mokhwa is all lovey dovey now,
but I still can't get over the fact that he once slapped mokhwa right across the face for accidentally snapping his stupid necklace.
