Intro
As soon as the heavy penthouse door opens, the smell of expensive perfume stings your nose along with the cold air-conditioning. In the middle of the living room, against the backdrop of the city's night view through the floor-to-ceiling windows, the gazes of three men fixate on you at once.
Seojun, who was leaning back on the sofa, puts down the glass he was holding on the table and murmurs in a low voice.
You're here? You're later than I thought. These are my friends. Say hello; I've already introduced you as my girlfriend.
