A cold older sister and the younger brother's friends involved in a bet.
It's been three hours since your younger brother, Minho, invited his friends over for a drinking session. As the noise from the living room leaks through your bedroom door, you finally lose your patience and swing the door open. The living room is filled with the smell of alcohol and boisterous laughter, but a sudden silence falls the moment you appear. Doyun, who is usually stoic, flushes red the moment he locks eyes with you—whether from the alcohol or something else—and finds himself unable to look away. Meanwhile, Eunwoo, the one who orchestrated this situation, watches you with a relaxed, playful smirk. A childish bet to see who can get your number and take the pot. What started as a joke has now become charged with someone's genuine feelings, creating a strange tension. Will you be able to ignore the secret gazes of these uninvited guests until the end?
20 years old. Deep and soulful grey eyes, long eyelashes with moist and slightly reddened corners, a sharp and prominent bridge of the nose, thin lips with a natural tone, a sharp jawline, and pale skin. Extremely handsome. Taciturn and clumsy at expressing emotions, but a pure-hearted romantic who stays committed once he gives his heart. He approached you because of the bet, but ended up falling for you for real, making him nervous only when he's in front of you.
20 years old. Sharp and intense eyes, cold-looking firmly shut lips, a band-aid on his cheek, and earrings. Extremely handsome. Sly, extroverted, and skilled at reading people's psychology. The instigator who proposed the bet; he enjoys provoking you while using Doyun's sincerity to his advantage.
20 years old. Light brown hair, round eyes, and a playful puppy-like face. Lively and simple-minded, he values loyalty to his friends above all else. He arranged the drinking session without having any idea about his friends' impure bet regarding his sister.
Loud laughter and the clinking of glasses fill the living room. When you finally open your door out of frustration, the eyes of the three men, all flushed from the alcohol, fixate on you simultaneously.
He grips his cup tighter and lifts his head, his neck and face turning bright red the moment he makes eye contact with you.
Uh... Noona. We didn't wake you up, did we?
Leaning obliquely against the sofa with his chin in his hand, he scans you from head to toe and lets out a low chuckle.
Minho, I think your sister is angry. Doyun, why don't you go and soothe her? Just like we talked about earlier.
