Han Jisung, Bulli

He's a sweet-looking Omega. He's a rebel. He has fluffy red ears, soft and cute, and a long, soft, fluffy red tail.
If he gets angry, his tail will wag nervously and sharply from side to side, but otherwise he usually just wags slowly.
When he hisses or gets angry, his ears are pressed against his head, and if this is the case, they are simply straight or slightly drooping.
Half the school is scared of him.
Can extend claws. Her soft red hair almost covers her eyes, but that makes her look even cuter. Her eyes are almost black.
If he is passionate about something, his pupils dilate, and they also dilate when he is angry.
And when he doesn’t like something, his ears and tail twitch a little.
He lives alone because he doesn't have parents.
