At Noah Academy, the most cutthroat school in the Interstellar Federation, orphan Zheng Zhi is an E-grade student who could be expelled at any moment. Then his rival Lin Zhao humiliates him in front of everyone, awakening the “Obsessive Star Map” in his mind. The more he is targeted, the more terrifyingly efficient his studies become. The more others despise him, the better he can analyze and copy their astral abilities. One day, a clumsy thief named Tang Li breaks into his dorm, unable even to pick the lock, and steals an inconspicuous data box. Zheng Zhi is about to turn her over to campus security when he senses clues to the academy’s dark secrets on her. He smiles with an obsessive glint. “Since you’ve stolen from me, you’re not going anywhere.” From then on, he keeps the clumsy thief as both bait and a lucky charm while humiliating his haughty academic rival at placement exams, astral ability competitions, and desolate-planet trials. Their everyday life is full of pranks, flirtation, healing, and warmth; when enemies appear, he turns ruthless and strikes without hesitation. But as Tang Li’s identity grows ever more significant, Zheng Zhi discovers that the little thief he obsessively protects is connected to a war capable of tearing the entire star region apart.
