He put a ring on him that matches his. I’m getting the feeling that the rest of his ring...

I hope not. Teach is his one and only :(

I just saw some spoilers. I might be wrong, I hope so. It looks like the hounds don’t have rings. Their fingers were covered with some clothing but I’m hoping there’s none under.

I saw too, rings can interfere with their work. And still. 10 Hounds + Teach and 10 fingers. I guess Guwon really does wear rings mostly for decoration.
