Mark Stuart made a horrifying discovery: he had been reborn as the game's mid-boss. In the original story, he was destined to be condemned by his own daughter, Forsina—a girl known as the "Ice Princess." Haunted by memories of how coldly he had treated her in the past, he becomes determined to rewrite his fate by winning her genuine affection. Through his considerate gestures and earnest efforts as a duke, his daughter slowly begins to trust and love him again. However, his devotion spirals out of control, and before long, her love grows far deeper—and far heavier—than he ever anticipated.
