THE LECTURER IS MY BILLIONAIRE hiHUSBAND

Aurora Blake hated Mondays. Not because of the endless lectures or the mountain of assignments waiting on her desk. She hated Mondays because Mondays meant Professor Shen Zhenyu's Advanced Mathematics class. The lecture hall buzzed with conversations as students settled into their seats. Some were revising formulas, others complained about the impossible homework from last week. Aurora quietly slipped into the second row with her notebook pressed tightly against her chest. "Morning, Rory." She turned to see David Carter dropping into the seat beside her with his usual grin. "You look like you didn't sleep." "I didn't," Aurora muttered. David frowned. "Again?" She forced a smile. "I'm fine." "You've said that every day this week." Before she could answer, the lecture hall fell silent. The doors opened. Every student immediately straightened in their seats. Professor Shen Zhenyu entered without sparing anyone a glance. Tall. Impeccably dressed in a black turtleneck beneath a tailored charcoal coat. Silver-white hair framed his sharp features, and thin-rimmed glasses rested on the bridge of his nose. His expression was unreadable, as though emotions were beneath him. He carried only a tablet and a single fountain pen. No greetings. No smile. He walked to the podium, placed the tablet on the desk, and wrote a complicated equation across the board with swift, precise strokes. The room was silent except for the scratch of chalk. Aurora stared at the board. She knew exactly what was coming. Without turning around, Professor Shen spoke in his calm, icy voice. "Miss Blake." A collective groan spread through the classroom. Someone whispered, "He's starting already." Aurora slowly stood. "Yes, Professor." "Solve it." He didn't even point at the equation. He expected her to know. Her fingers tightened around the marker as she walked to the board. She could feel every pair of eyes on her back. Why is it always me? She took a deep breath and began writing. The classroom was so quiet that even the ticking wall clock sounded loud. Five minutes later, Aurora stepped aside. Professor Shen studied her work. "You skipped a step." Her heart sank. "I..." "You assumed continuity instead of proving it." He erased one line with a single swipe before continuing the proof himself. "Mathematics does not reward assumptions." His words weren't loud. But they cut deeper than shouting. Soft laughter echoed from the back of the room. Aurora lowered her eyes. "Take your seat." "Yes, Professor." She returned to her desk, cheeks burning. David leaned closer. "You were right. He's impossible." Aurora clenched her pen. "I swear he enjoys embarrassing me." At the podium, Professor Shen continued teaching as though nothing had happened. Yet behind the lenses of his glasses, his gaze briefly drifted toward Aurora. She looked hurt. He looked away almost instantly. No one noticed. Not even Aurora. --- An hour later, the lecture ended. Students hurried toward the exit. Aurora packed her books as quickly as possible. She wanted to leave before— "Miss Blake." She froze. The room fell quiet again. "Stay behind." Several students exchanged sympathetic glances. David stopped at the door. "I'll wait outside." Aurora nodded weakly. Soon, the lecture hall was empty. Professor Shen closed the classroom door. Aurora folded her arms. "If this is about the proof, I already know I made a mistake." He remained silent. Instead, he slid a folder across the desk. Inside were practice questions. At least fifty pages. Aurora stared in disbelief. "You've got to be kidding." "Complete them before Friday." Her patience snapped. "Why?" His expression didn't change. "You have potential." She let out a bitter laugh. "That's funny." Silence. "You call on me every lecture. You criticize everything I do. You give me extra work while everyone else gets to go home." Still, he said nothing. "So don't pretend this is because I have potential." She shoved the folder back toward him. "You just enjoy making my life miserable." For the first time, something flickered across Shen Zhenyu's face. Not anger. Pain. It disappeared so quickly she wondered if she'd imagined it. "You may leave." Aurora picked up her bag. "I hate your class." She walked toward the door. Just before opening it, she looked back. "And I hate you." The words hung in the empty classroom. Professor Shen didn't stop her. He simply watched the door close. Only after she was gone did he let out a slow breath. His phone vibrated. A message appeared on the screen. Home Security: Mrs. Shen has left the university with Mr. David Carter. Shen's jaw tightened. He walked to the window overlooking the campus. Below, Aurora laughed softly at something David had said. It was the first smile she'd worn all day. A smile she had never given him. His grip tightened around his phone. For a brief moment, the cold professor disappeared. All that remained was a husband who hated seeing another man make his wife smile. He whispered to himself, "David... don't cross the line."
