The North Duke Is a Cat - Unisex Long Sleeve Tee

The Story Behind the Design

In 2024, fans gave one idol a striking nickname: “The North Duke.”
The title came from the world of Korean web novels and webtoons — where the North Duke is a cold, powerful character, skilled in battle, with a sharp black hairstyle and an intimidating aura. For many fans, this image perfectly matched the stage presence of one member of an eight-piece global K-pop group. He looked like a 2D hero who had stepped right out of a novel.

But here’s the twist: off stage, his real personality is nothing like a dark warlord.
He loves sweet desserts, shows lots of playful charm, and acts more like… a cat.

That’s where the fandom joke comes in:
“The North Duke is a cat.”
It’s a phrase that flips the intimidating nickname into something warm and endearing — and fans love it all the more.
