Hi! That’s normal, and actually really realistic! Fighters tend to have their ears squeezed on the flor while fighting. So as a responce, a liquid naturally flows in the ears to protect them and make them stronger and harder, as an immune system against constant exposure. It's painful, and letting that liquid in there for a long time make it impossible to remove. (You can check on internet, most fighters have this kind of ears)
btw its so funny to me how the ears are drawn jaekyung's worse, it looks like it was stung by 3 bees
