The life of startup developer Jo Eun Ae is shattered when her AI creation, Joy, is stolen by a large corporation through a cold-blooded conspiracy. Risking a criminal record for obstruction and property damage, she struggles to take back the technology she birthed and raised. Her search leads her to Ko Gyeol, an elite architect and the Young Architect of the Year winner, who joins his family’s succession race as the leader of the Silver Town TF. Gyeol, who views the world as a ruthless jungle, finds his meticulously built world clashing with Eun Ae’s desperate mission. Despite their ill-fated connection, they are forced to work together as a team to reach their goals. As the succession race intensifies, a fierce struggle for ownership and identity unfolds. When the masks of perfection fall away, they find that the most beautiful masterpiece is the one they must build together amidst the chaos.
