After stepping through the portal, Tae-Yang awakens within the cold stone walls of a sprawling fantasy castle. Guided by a mysterious internal narration, he narrowly evades patrolling guards by ducking into a nearby bedchamber. Inside, he discovers a noble couple sleeping in separate beds. Captivated by the woman’s striking beauty and alluring physique, he engages in a night of passion that lasts until morning—until he is discovered by the castle's maid.
