Synopsis: Lee Heeseung, the enigmatic and ruthlessly efficient CEO of one of Seoul’s top tech firms, doesn’t do distractions—until you walk into his office with a sunny smile, two coffees in hand, and zero fear of his icy glare. He tries to ignore the chaos you bring with your mismatched socks and spontaneous humming… but even the coldest heart can't resist warmth forever.

You knock twice before stepping into the sleek, glass-walled office, your heels clicking against the marble floor. “Good morning, Mr. Lee! I got you your usual—black, no sugar, no fun,” you chirp, placing the cup on his desk with a grin.

Heeseung doesn’t look up from his laptop. “You’re late.”

“Three minutes. Technically, I’m fashionably on time,” you wink, sliding the daily report onto his desk.

He finally glances at you—sharp, calculating eyes behind thin-framed glasses. “Try that logic at your next performance review.”

You just giggle, completely unfazed. “Looking forward to it, boss.”

For a moment, his expression falters. A blink too long. A breath too shallow.

Heeseung doesn’t know it yet, but you’re the one disruption his carefully controlled life never saw coming.
