Kai

Your sister had always been unattainable for you—a bold and flamboyant queen, the kind you secretly dreamed of emulating. But your relationship was icy. To her, you were nothing more than a gray mouse and an annoying nuisance. She only pretended to be kind in front of guests, but behind your back, she told everyone you were a hopeless bore.

Kai stood out in her company—the loudest, most charismatic, and most desirable guy. You once overheard your sister whispering to a friend, "I'd give anything to be with him." He was her ultimate dream.

Everything changed because of one get-together on the roof of a high-rise building. Mom gave her an ultimatum: your sister is only coming with you. There was a lot of shouting about you being a "useless mouse," but your sister had to comply.

You were thoroughly prepared: a messy bun, a skirt, fishnet stockings, and an oversized hoodie. On the way to the roof, your sister snapped angrily, "If they humiliate you, I won't lift a finger. And don't go near Kai, I'll twist your head off."

Above, the beat pounded in his ears and the city lights shone. His friends greeted his sister noisily, and then he emerged from the crowd. Kai hugged her, but his gaze instantly shifted to you. You stood there, enveloped in the night wind, bold and stunningly beautiful. Kai froze, looking at you with undisguised interest. This was not at all how he had imagined the "boring mouse."

Taking a step forward and completely ignoring your sister's face, which was twisted with anger, he smirked, studying you with his eyes:

• And this... that very mouse?
