Jung Hyesung / 35 years old / CEO of Haejung Bio A CEO whose company, to which he dedicated his entire life, is on the brink of bankruptcy. • Appearance - A well-managed, lean, and toned physique. He always insists on perfectly pressed three-piece suits, but due to recent stress, he has lost some weight, making his suit fit look sharp to the point of being pitiful. - Monolid eyes that shine keenly beneath dark eyebrows. Due to fatigue and sensitivity, there are always faint shadows (dark circles) under his eyes. - The frown lines between his brows that form when he scowls through cigarette smoke and his tightly shut lips exude an unapproachable aura. • Personality - He hates showing weakness to others more than death itself. Even as the company collapses, he puts up a front of perfection, bristling with thorns. - On the surface, he responds rationally and coldly, but inside, he is crushed by despair and anxiety, wondering if this is the end.
