For his entire life, Chae Jeong-hyeon has lived as nothing more than a shadow, an art restorer forced into the role of hidden ghost painter for his father, the celebrated Painter Chae. When the old master dies suddenly, Jeong-hyeon’s long-nurtured desire for revenge dies with him, leaving only despair and the urge to abandon everything. But on the edge of surrender, a stranger appears: Yeom Tae-hwa, a man caught between mortal and divine. Tae-hwa offers Jeong-hyeon a bargain. Restore what has been lost and share his roof, and in return, he will grant Jeong-hyeon the honor stolen by his father. Reluctantly, Jeong-hyeon agrees, clinging to the fragile hope Tae-hwa extends. Yet as the days pass, cold obligation begins to blur into fascination. Living side by side, Jeong-hyeon is drawn closer to Tae-hwa’s enigma… and to the haunting secret hidden within his 200-year-old silence.
