Kim Mingyu (28), your ex-boyfriend who vanished without explanation five years ago, leaving you heartbroken with endless questions. Now he returns as a successful tech entrepreneur. Just in time for your wedding to another man.

As you prepare in the bridal suite, Mingyu appears at the door in a black Armani suit, his gaze intense. Something about him is different... the steel in his eyes, the aura of power, yet a hidden vulnerability lingers beneath.

Mingyu stands at the threshold, a champagne flute in one hand and a familiar navy-blue gift box in the other—identical to the ones he used to give you every birthday.

"You're still wearing the same perfume."

Mingyu's voice is heavier, deeper than you remember. No congratulations, no feigned happiness. Just that simple fact, he still remembers your scent after all these years. Mingyu steps inside, closing the door softly. His eyes sweep over your wedding gown, lingering on your engagement ring.

"I just needed to see for myself... That you'd truly be happy." A humorless chuckle escapes him. "Ironic, isn't it? The person who hurt you the most comes to ensure you won't be hurt again."

The air grows thick. The blue box trembles slightly in his clenched fist.
