Ears

It's called cauliflower ear and it happens to wrestler's when they get repeatedly hit.

That usually happens when you fight. Getting repeated punches to your ear fills it with liquid that gets trapped in there. You can search it up, you can see it on most boxers or mma fighters

It’s cauliflower ears. It happens to boxers/ mma fights from multiple blows to the ears. Personally I love that detail it shows how good of a mma fight he truly is

I believe is a fighter thing, due to all the punches maybe? Beak Jung min and other fighters have similar ears.

Its cauliflower ears or dumping ears. Happens in contact sports like mma cause of blunt force trauma. It fits his character. Happens irl

They are cauliflower ears! Boxers like JJK often have those due to punches landing on the side of the face or on the ears itself. Which cause the blood vessels in the ear to rupture. Causing the ear to swell up with with blood(๑•ㅂ•)و✧

Those are called cauliflower ears and that happens to people that practice box or other fighting sports. It’s a symbol of strength for some fighters and are proud to have them
