The flirtatious girl is done flirting; Mr. He is now obsessed with her.

When He Yun Shen and Bai Yi Shu's eyes met, their gazes paused for a moment before returning to normal.

He placed the book on the podium, his simple white shirt outlining his slender figure, and a low-key black watch on his wrist. Sunlight fell on his well-defined profile, making him appear less aloof than at the banquet and more composed and refined.

"So handsome!"

"I heard he just turned 30 and is still single."

Bai Yishu twitched the corners of her mouth, completely ignoring the discussion of the girls beside her. She picked up a pen and scribbled on her notebook, feeling utterly puzzled as to why He Yun Shen was here.

As the heir of the He family, he not only possesses tens of millions in assets, but also enjoys power, wealth, and fame. Now, he has actually come to a university to become a professor. Is it just to experience life?

Could it be... because he knew I studied at this university...?

Bai Yishu shook her head, immediately snapping out of her chaotic thoughts, and inwardly mocked her own wishful thinking.

She couldn't help but look at He Yun Shen standing on the podium, her gaze falling on his hand holding the chalk, his fingertips clean and slender, his movements crisp and neat.

Images from the past kept flashing through Bai Yishu's mind: his smiling and talking with a wine glass at the banquet; his indifferent tone when he rejected her; and his composed posture as he lectured on the podium now. These images intertwined, making her feel confused and unable to concentrate on the lesson.

"This student..."

He Yun Shen stopped writing on the blackboard, turned around, and his gaze landed precisely on Bai Yi Shu.

"You answer this question."

Bai Yishu stared at a line of words on the blackboard, her mind blank.

"have no idea."

He Yun Shen put down the chalk, slowly walked down from the podium towards Bai Yi Shu, his leather shoes making a clear sound on the ground.

"Then this student needs to pay close attention. This is a very basic concept, and I don't want to hear you answer 'I don't know' again."

He stood in front of Bai Yishu's desk, lightly tapping the surface with his fingertips.

"Come to my office after class."

Looking at He Yunshen's well-defined fingers, Bai Yishu couldn't resist the urge and, under the cover of her book, gently hooked her little finger around him.

"Okay, Professor He."

He Yun Shen's body stiffened for a moment, a dangerous glint in his eyes swept across Bai Yi Shu's face, and he subtly withdrew his hand, returning to the podium.

"Then let's continue..."

When he spoke again, his voice was calm, but with a hint of suppressed tension.

After class, Bai Yishu packed up her textbooks and went to He Yunshen's office.

"Come in."

Bai Yishu slowly opened the door and curiously poked her head in.

The large office contained only one desk, indicating that it was He Yun Shen's private office. The decoration and layout looked much the same as the other teachers' offices.

Seeing Bai Yishu close the door, He Yun Shen slowly raised his eyes and leaned back in his chair.

"Bai, if you can't answer the questions in class, is it because you weren't paying attention, or are you doing it on purpose?"

Bai Yishu walked to the desk.

"Isn't Professor He a businessman? Why is he teaching?"

He Yun Shen chuckled lightly, as if he had expected Bai Yi Shu to change the subject.

"The school extended a warm invitation, and I'd like to experience a different role."

He got up and slowly walked to the window, his back to Bai Yishu.

"However, this doesn't seem to concern you, does it? I haven't answered your question yet."

Bai Yishu shrugged and said casually, "Because I'm stupid."

"Is Miss Bai stupid?"

He Yun Shen turned around, walked around to Bai Yi Shu's front, and looked down at her from above.

"I think Miss Bai is too smart; she knows how to attract the professor's attention in class."

He leaned closer to Bai Yishu, his deep voice ringing in her ear.

"Since you're so slow, I'll give you special tutoring, how about that?"

The warm breath He Yun Shen exhaled into her ear made half of Bai Yi Shu's body feel tingly and numb, and she forcibly suppressed the throbbing in her heart.

"Okay, then Professor He, you'll have to teach me step by step."

A playful glint flashed in He Yun Shen's eyes, and he took a few steps back.

"Bai, you really don't hold back."

He pulled a book from the bookshelf behind him and handed it to Bai Yishu.

"Read this book first, and mark the parts you don't understand."

"Next lesson... I'll teach you step by step again."

The bell rang again, and Bai Yishu hugged the book to her chest and walked out of the office.

Bai Yishu.

He Yun Shen suddenly called out to her, and just as she was about to close the door, he walked to her side, placed his palm on the door frame, and partially surrounded her between himself and the door frame.

"Remember what I said, study hard. And..."

He Yun Shen remained silent for a moment, then lowered his voice, which was slightly hoarse.

"Don't touch me like that again next time."

After speaking, he straightened up, indicating that Bai Yishu could leave.

Bai Yishu knew he was referring to the time she touched his hand in class earlier. Although she did it on purpose, no one could resist doing that.

After returning to her dormitory, Bai Yishu checked her class schedule. Fortunately, He Yunshen only taught one class a week, so she wouldn't have to see him so often.

Bai Yishu knew all too well how attractive He Yunshen was to her; even if he just stood there motionless and silent, she could be infatuated with him all day long.

In order not to let all her recent efforts go to waste, Bai Yishu decided to continue to stay far away from him except during class time.

On the weekend, Bai Yishu brought a few books to the library, walked to the back row of empty bookshelves, sat down, and began to read the books He Yunshen had given her.

Before she had even finished reading half of the book, a slow sound of footsteps approached from afar, and the familiar scent of perfume wafted through the air. Bai Yishu knew who it was without even looking.

"Bai is really hardworking."

He Yun Shen approached quietly, his gaze falling on the open book in Bai Yi Shu's hand. Suddenly, he leaned down and whispered in her ear.

"Did you understand? Do you need the professor's personal guidance?"

Before Bai Yishu could answer, He Yunshen straightened up and casually flipped through a book he had just picked up from the bookshelf.

"Coming to the library all weekend, Bai really doesn't have any other entertainment activities."

Bai Yishu closed the book and stood up from the ground.

"What about the professor? Instead of focusing on being a businessman, is he planning to become a full-time teacher?"

"Is Bai very concerned about my career plans?"

He Yunshen put the book back on the shelf and leaned slightly towards Bai Yishu.

"Businessman or professor, to me they are just identities."

"However... what would you think if I said I became a professor for certain people?"

Bai Yishu's gaze froze, and for some reason, she hoped he was talking about her; a sense of anticipation welled up in her heart.

"Some people?"

He Yun Shen straightened up, his eyes fixed on Bai Yi Shu, observing her reaction with great interest.

"Does Bai think it's possible that he/she might be one of 'certain people'?"
