The landlord has multiple personalities and wants everyone to pay him.

The living room of Yunduanyuan was quiet in the morning.

Ye Shu frowned slightly as she sat on the sofa, holding a freshly brewed cup of jasmine tea.

He had been holding that position for a while, not drinking, just sitting there. His eyes glanced sideways at Xiao Nuan sitting next to him.

Xiao Nuan also held a cup of tea, the same mug as Ye Shu's, with a few jasmine flowers floating inside.

Ye Shu tentatively grasped the cup by the handle, raised it to her lips, blew on it gently, and took a small sip, but her eyes were constantly fixed on the side.

Xiao Nuan also held the cup by the handle, raised the teacup to her lips, gently blew on it, and then took a small sip.

It was exactly the same action Ye Shu had just performed.

Ye Shu blinked, put down the cup, and scratched the back of her head slightly to the right with her right hand.

Xiao Nuan next to her also put down her cup, raised her right hand, and scratched the back of her head slightly to the right. She scratched in the exact same direction, and after a few scratches, she did it perfectly.

Ye Shu took a deep breath, feeling a throbbing sensation in her temples.

This strange situation started after they woke up this morning.

He brushed his teeth, and Xiao Nuan stood next to him with her toothbrush in front of the mirror. He brushed his left side, and Xiao Nuan brushed her left side too. He rinsed his mouth, and Xiao Nuan rinsed her mouth too.

Even during meals, he would take a bite of a steamed bun, and Xiao Nuan would also take a bite, her eyes fixed on his mouth the whole time, even adjusting the frequency of her chewing the buns to be exactly the same.

At first, Ye Shu thought Xiao Nuan was just in a good mood and didn't know what she was playing.

But this learning session could last for several hours, following the teacher wherever they went.

Moreover, Xiao Nuan is making rapid progress, her imitations are becoming more and more accurate, and eventually she even learned the sound of her own sneezing.

That's a bit weird. Imagine your girlfriend wakes up in the morning and turns into someone who can only mimic your behavior, and does it incredibly well. Wouldn't you be scared?

Ye Shu felt uncomfortable all over.

There seems to be a psychological theory that when you know you're being watched and imitated, you start to feel inexplicably itchy all over your body.

Ye Shu felt very itchy and reached out to scratch her neck.

Xiao Nuan next to her also reached out and scratched her neck.

Ye Shu reached out and scratched his leg, and Xiao Nuan also reached out and scratched her leg.

Ye Shu finally couldn't take it anymore; he felt like ants were crawling all over him.

He turned his head and looked at Xiao Nuan.

Xiao Nuan also turned her head at the same time and looked at him. Her clear big eyes were fixed on Ye Shu, as if waiting for his next move.

Ye Shu took a deep breath, composed herself, and forced a smile. After all, it was Xiao Nuan opposite her; nothing Xiao Nuan did strangely wasn't surprising, she must have her reasons.

"Little Nuan..."

"Um?"

"That thing"

Ye Shu drew a circle with her hand, then pointed to herself:

"Why are you copying me? Why do you do everything I do?"

Xiao Nuan blinked, and Ye Shu didn't make a sound, because he knew Xiao Nuan was thinking.

Xiao Nuan has a habit of blinking more frequently when she's thinking. Ever since Ye Shu discovered this habit, every time Xiao Nuan is thinking, Ye Shu seems to hear the sound of a computer fan spinning.

"Learning from you?"

Xiao Nuan finished thinking, then shook her head and said emotionlessly:

"It's not learning, it's behavioral training in sync."

"Huh...training? What kind of training?"

Ye Shu didn't understand.

"According to multiple studies in sociology, psychology, and behavioral science, couples who live together for a long time and have a close emotional bond will gradually become similar in language patterns, micro-expressions, body language, behavioral habits, and even facial muscle movements unconsciously. This phenomenon is often referred to as 'couple resemblance' or 'partner synchronization effect.' Its causes involve emotional contagion, mirror neuron activity, habit convergence caused by long-term cohabitation, and subconscious mutual identification and imitation."

Looking at the expression on Ye Shu's face that was somewhere between "I think I understood" and "I'm completely clueless," she summarized it in more concise terms:

Simply put, couples with good relationships tend to become more and more alike.

It's getting more and more like...

Ye Shu felt that the probability of her becoming more and more like Xiao Nuan was not very high.

"Uh... I think I understand."

Ye Shu nodded. Although he hadn't quite absorbed that long passage, he still understood the concept of a couple looking alike.

"But what does this have to do with... you learning from me now... uh, training?"

The relationship is clear.

Xiao Nuan replied:

"Given that we have established a romantic relationship and will eventually get married, becoming husband and wife, I am actively engaging in induced training to optimize the harmony and understanding of our married life in advance. Through conscious behavioral imitation and synchronization, we can accelerate the mapping and learning of each other's behavioral patterns by our neural networks, shorten the natural adjustment period, and greatly help in building a stable, efficient, and low-conflict married life."

Ye Shu opened her mouth, feeling as if the fan in her brain had started spinning.

This time he understood. Having lived with Xiao Nuan for so long, he was able to extract the core ideas from her long list of experimental reports.

The core idea is that she wants to resemble her husband, so she's starting to imitate him now, aiming to achieve that perfect look in one go.

This silly child...

No, in some ways, I'm the silly kid in front of Xiaonuan...

Ye Shu sighed helplessly, raised his hand and ruffled Xiao Nuan's hair, which felt nice to the touch because it had just been washed.

"Xiao Nuan, this 'couple's resemblance' isn't something one person can force by imitating the other, you understand? It's something that develops naturally over time as two people live together. You have to let nature take its course."

Xiao Nuan let Ye Shu's hands do whatever they wanted to her head, messing up her hair without resisting, and just stared at Ye Shu.

A few seconds later, she nodded:

"I understand. You mean that partner synchronization should be an emergent characteristic that arises from long-term cohabitation, rather than a goal that can be achieved through short-term behavioral imitation. The focus should be on the interaction of the process, rather than the state of the predetermined outcome."

"Ah... I think so?"

Ye Shu grinned. He really didn't understand what that sentence meant, but it should be roughly correct, right?

He withdrew his hand, picked up the jasmine flower on the coffee table, and smelled it. He noticed that Xiao Nuan next to him did not imitate him by picking up her teacup and smelling it this time, and he breathed a sigh of relief.

Ye Shu felt incredibly proud of herself. How could she be so amazing? She could even handle Xiao Nuan. Ye Shu suddenly imagined the conversation between the two of them earlier.

He and Xiao Nuan were standing in a science laboratory, both wearing white lab coats and goggles, discussing something with an instrument.

I must say, chatting with Xiaonuan is actually quite enjoyable.

I never imagined that my childhood dream of becoming a scientist, which was forced upon me by my teacher, would actually come true with Xiao Nuan.

He took a sip of tea, preparing to relax, when Xiao Nuan spoke up again beside him:

"So, Ye Shu, when are we going to have a child?"
