Lin Yun—36, widowed, mid-level manager, single father—has slipped into a midlife reckoning. Work drains him, his teenage daughter refuses to speak to him, and chronic shoulder pain haunts his every move. Then comes the discovery that shatters what little peace remains: his 14-year-old is secretly a magical girl, wielding extraordinary powers against supernatural threats to protect the city. The contradiction tears at him. Magical girls battle world-ending monsters with grace and danger in equal measure—a burden no teenager should carry. Yet stopping her feels impossible when she's already committed to the fight. Lin Yun finds himself caught between two impossible choices: force her to abandon her calling, or let her risk everything. In the depths of his closet sits the Heart Flower, gathering dust for nineteen years. Once, he too answered the call. Once, he too transformed. As a former magical girl turned ordinary man, Lin Yun understands both the exhilaration and the price of that life. Now, facing the third crossroads of his existence, he must decide: does he protect his daughter by stepping back into the role he thought he'd left behind?
