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

Bai Yishu looked around to make sure no one was watching before continuing.

"I'm not that presumptuous."

He Yunshen raised an eyebrow, placed one hand on the bookshelf, and partially surrounded Bai Yishu.

"But I feel like Bai has always been very clear that she is special to me."

"Professor He, are you admitting that I treat you specially?"

"What's the point of admitting it?"

He Yun Shen leaned down and stopped just before his face was almost touching Bai Yi Shu's.

"Isn't this exactly what Bai wanted to hear?"

"But you have to understand, being special... doesn't necessarily mean being special in a good way."

Bai Yishu watched him straighten up and resume his usual aloof demeanor.

"Is that bad?"

He Yun Shen smiled slightly, a hint of cunning in his eyes.

"For you, being remembered by me, being noticed by me, even if it's a bad thing, doesn't matter, right?"

He paused, then suddenly lowered his voice, speaking almost into Bai Yishu's ear.

"That's your problem, Bai Yishu."

"You want me so much that you don't care about the methods or the consequences."

Bai Yishu gave a soft snort and turned to look at He Yunshen.

"Isn't this something you tacitly approved?"

He Yun Shen's eyes sharpened, and he suddenly grabbed Bai Yi Shu's wrist and pulled her close to him, his voice low but clear.

"Bai Yishu, don't overestimate your charm. I just want to see how far you can go."

He released Bai Yishu's wrist, and with his other hand gently wiped the spot where he had just touched her, his disdain evident in his eyes.

"Now I see it."

Bai Yishu felt a pang of pain in her heart from his gaze, but she no longer acted coquettishly or spoiled towards him as she used to.

"In that case, Professor He, please push me away, so that I can never get close to you again."

A complex emotion flashed across He Yun Shen's eyes, which was then covered by a cold smile at the corner of his mouth.

"Is this what you wanted?"

He Yun Shen stepped forward, placed his hands on the bookshelves on either side of Bai Yi Shu, and trapped her in his arms in an extremely ambiguous posture.

"Then I'll do it thoroughly, so you'll never dare to have any improper thoughts again."

Bai Yishu stared coldly at him. Just then, a student walked by at the other end of the bookshelf, and He Yunshen released her at the opportune moment.

Bai Yishu bent down to pick up the books from the ground, tucked a stray hair behind her ear, and nodded slightly to He Yun Shen as if nothing had happened.

"Well then, Professor He, I'll be going now."

Bai Yishu walked out from one side of the bookshelf without looking back, her slender figure gradually disappearing into the distance under He Yunshen's gaze.

Only after she was out of sight did He Yun Shen loosen his fists, which were clenched at his sides, and walk towards the other side of the library, each step as if he were suppressing some strange emotion in his heart.

Professor He Yunshen's elective economics course is held every Friday afternoon, and he does not appear at school at any other time except for this day.

Bai Yishu breathed a sigh of relief. Ever since they met at the library that day and had a falling out, they hadn't heard from each other again.

Even when they were with He Wanqing, they both automatically avoided mentioning the name He Yunshen. Although they both wanted to know something from each other, he was like a taboo that prevented them from speaking.

It was Friday again. Bai Yishu picked up her books and stepped into the classroom. He Yunshen was already standing in front of the podium.

As classmates gradually walked in, He Yunshen didn't even look up; he was simply tidying up his books.

As Bai Yishu passed the podium, she couldn't help but glance at him before walking to the back row and sitting down.

"Attend class."

He Yun Shen glanced at the whole class, his gaze lingering on Bai Yi Shu's seat for a second before quickly looking away.

His lectures were calm and professional, as if nothing from the previous week had ever happened.

"Bai Yishu, my classmate."

He Yun Shen suddenly called out to Bai Yi Shu, who was taking notes, and drew a long line of chalk under a line of words on the blackboard.

"You answer this question."

"You should know about variations and applications of this formula, right?"

Bai Yishu nodded.

"Then please come up and write it on the blackboard."

Bai Yishu put down her pen, got up from her seat, and walked towards the podium.

She took the chalk He Yun Shen handed her; the warmth of his fingertips still lingered on it.

Bai Yishu wrote the formula on the blackboard, but Yu Guang could never ignore the gaze beside him.

Seeing that Bai Yishu had written the correct answer, He Yunshen's lips curled up slightly.

"Hmm, not bad."

"This formula is very important; everyone must master it."

Then, he said to Bai Yishu, who had returned to her seat, "Come to my office after class."

When Bai Yishu heard He Yunshen call her to his office again, she winked and made a face at the male classmate sitting next to her.

He Yun Shen keenly noticed her subtle expression, coldly watching her interact with the boy next to her. He put down the chalk, crossed his arms, and watched her with a leisurely air.

"Is there a problem, Bai?"

Bai Yishu shook her head as she looked at the stares from her classmates.

"Professor, of course, no problem."

Seeing He Yun Shen turn around and continue his lesson, Bai Yi Shu glared at him.

Not knowing what he wanted to see her about again, Bai Yishu obediently went to the office after class.

Do you know why I called you over?

Bai Yishu closed the door and walked to her desk.

"Was it because I didn't behave well in class?"

He Yun Shen chuckled softly, his voice tinged with amusement.

"You did very well in class, didn't you?"

"So...you missed me?"

He Yun Shen chuckled as if he had heard something funny, but his eyes grew even colder.

"Bai Yishu, you're really confident."

He got up and walked to Bai Yishu, trapping her next to the desk.

"I called you here so that you would understand that our farce is over."

Seeing that Bai Yishu remained silent, He Yunshen recalled her interaction with the boy next to him in class earlier, and tightened his grip on the table.

"So, whether it's the eldest daughter of the Bai family or... anyone who tries to climb into my bed, you'd better put away those inappropriate thoughts and stay away from me."

The indifference in He Yun Shen's eyes seemed to be a form of revenge for what Bai Yi Shu had said to him in the library that day.

He even deliberately brought up things that embarrassed her, showing that he was determined to get rid of her.

I just didn't expect that even knowing the outcome would still cause my heart to ache so much.

Bai Yishu secretly clenched the hem of her clothes, forcing a smile as she said, "Alright, then so be it, Professor He."

He Yun Shen's expression stiffened slightly, a fleeting, inscrutable look crossing his face before returning to its usual coldness in the next second.

"Very good, I hope you keep your word."

He stood up, straightened his shirt cuffs, and looked at Bai Yishu with icy eyes.

"Bai, you can leave now. Remember, don't show up in front of me unless it's in class."
