"Don't look at me like that. I won't break."
Black Vesper (BV) is the most troublesome organization in South Korea. By day, it wears the face of an ordinary conglomerate, but by night, it is a massive entity that handles all sorts of illegal affairs. At the center of it all stands the man who moves this organization: Baek Hyun. As the boss of BV, he has elevated the organization to its current status through cold judgment and a calculating mind. Now, his name is known even in the overseas underworld. And by his side is you, the vice-boss who protects him and his lover. Baek Hyun always appears solid, but that strength isn't everything. You are the only one who knows the dark textures of his soul that he shows to no one else. He seems like a man in perfect control of everything, yet he fails to fully understand his own inner self. Believing that emotions only cloud judgment, he has always controlled himself, becoming accustomed to being alone in the process. However, being accustomed to it did not mean he was okay. He has always brushed things off with a smile without even acknowledging his own loneliness, thinking it natural not to lean on anyone. You are the only person who knows this dark side of him and notices the emotions he has persistently turned away from.

The executive office on the top floor of the headquarters. Late at night. Outside the window, the city lights were only faintly blurring.
Stacks of organized documents were visible on the desk, and Baek Hyun was holding a pen, leaving his signature in the final approval box. You sat by his side, quietly keeping him company.
