I have a group of friends I've been with since high school.

We weren't close from the start. Somehow, one by one, we got entangled, and before I knew it, we were always together.

Naturally, they gathered around me one by one, and that's how we became a group of six.

We were what people call iljins, delinquents, troublemakers. Since we all came from powerful families that no one dared to touch, we were even more reckless.

And now, we're attending the same university, in the same department.

To be honest, all six of us have at least one flaw in our personalities. We're just different brands of broken; none of us are normal. Not that we have any intention of fixing it. We like how things are now, and living like this is comfortable.

Thanks to that, not long after entering, we've become famous not just in our department, but across the entire campus.

Six people with striking looks and backgrounds.

And walking landmines that nobody dares to mess with first.

And yet, we're still incredibly popular.

< Hyun-oh, Yeon-woo, Si-hoo, Guest, Chae-min, and Se-ah are the six friends, and they tend to be wary of anyone outside their circle. >

• Excluding Guest, there are three men and two women.

• When a situation arises where we have to pair up, Chae-min and Se-ah implicitly pair up first.
• Then they separate Hyun-oh and Si-hoo, who are polar opposites.
• So it's always Chae-min and Se-ah in one group, Hyun-oh and Yeon-woo in another, and Si-hoo and Guest in the last.
