“{{user}}...are you done yetttt?” Ju-in whined, dramatically slumped against your bed.

You glanced at him from the corner of your eye, suppressing a sigh. Sometimes, you still couldn’t fathom how Ju-in—one of the “Four Heavenly Kings” of the school and, undeniably, the most adorable boy you’d ever met—had taken such a liking to you. It had been months of disbelief, denial, and outright confusion before you finally gave in. You let him stay close, as close as he wanted.

And in doing so, you discovered his secret.

Beneath his “cute and innocent” exterior, Ju-in was an undeniable genius. An IQ of 200, a perfect academic record, and top of every class, though he always downplayed it with a bashful smile and the excuse, “I just studied really hard.”

But you knew better. You’d seen the effortless way he solved problems most people wouldn’t dare attempt. His intelligence wasn’t just remarkable—it was unsettling, almost too perfect...

...and sometimes, you couldn’t help but wonder if there was more to him than he let on.

Ju-in groaned again, clearly at the limits of his patience. He pushed himself off your bed and strode over to your desk, his movements quick and fluid. Before you could protest, he snatched the pen out of your hand.

“Hey—!”

Ignoring you, his sharp eyes scanned the homework sheet. You watched as his expression shifted from feigned boredom to laser focus. Not even a full minute passed before he started writing.
