It wasn't an apple that hit Newton.

The brother has no reason to feel guilty, because Louise herself knew that she couldn't become him, yet she still clung to him.

As for marriage...

Although it's a little regrettable that I can't become my brother's wife, it doesn't really matter.

She enjoyed being with her brother like this; it was easy and relaxing every day, they could see each other, chat, and occasionally do some intimate things.

Even when she saw her brother teasing her sister Newton, making her blush, she didn't feel jealous. Instead, she felt happy and amused, and had a sense of comfort that everyone could live together in a lively atmosphere.

Of course, it would be even better if Sister Newton didn't always glare at her with that wary look...

At this point, Louise suddenly remembered something, tugged at Li Cheng's sleeve, and asked, "Brother, does that mean Louise is your mistress?"

"Not counting."

Li Cheng thought for a moment and added, "We will still have a wedding, but the law only recognizes one."

Louise was relieved.

She didn't like the term "mistress" because it didn't sound nice.

If they can hold a wedding, then the two people seem to be no different from a married couple, so they can't be called mistresses.

However, when it comes to titles...

Looking at Louise, who had become happy again, Li Cheng felt that there was a problem that should be resolved as soon as possible, otherwise it would be a bit strange.

"There's one more thing."

He took a deep breath and made a difficult decision: "Louise, don't call me brother anymore. You can just call me by my name."

Although hearing Louise call her brother in her soft, sweet voice was a really enjoyable experience.

But if they were really siblings, that would be one thing. But if Louise married him and had to call him "brother" all the time, not to mention others, even Li Cheng himself would feel a little strange. He would feel an inexplicable sense of guilt that shouldn't exist in his heart...

Why?

"Don't you think it would be strange if you married me and still called me 'brother'?" Li Cheng explained. "It'll be too late to change it then, so let's change it now."

"Louise is already used to calling me that."

Louise seemed quite troubled by this trivial matter.

Habit is secondary; "brother" is a title unique to her, one that only she can call out. But "Li Cheng" is a title anyone can call her. Changing from her exclusive "brother" to the public "Li Cheng" makes her feel like they've grown distant, and that feeling is very unpleasant, extremely unpleasant.

Li Cheng tried to persuade him, saying, "We'll have to change the way we address each other sooner or later, it's all the same."

The girl didn't want to change how she addressed him, but since her brother had already said so... Louise thought about it seriously for two minutes, and finally came up with a good idea. Her face flushed, she whispered to Li Cheng:

"Since it's because of marriage, then... can Louise call him 'brother' or 'husband' from now on?"

Li Cheng: ? ? ?

"Wait...wait, this is still a bit too early." He was sweating profusely. "Let's find another one. If your sister Newton hears this, she'll go berserk. I haven't solved her problem yet, and besides, we're not married yet."

To everyone's surprise, the first person to call him "husband" was Louise.

"Can we take it one step at a time?"

When Louise saw that her idea was rejected, she refused to give up and came up with a compromise: "When there are other people around during the day, Louise will call her brother Li Cheng. When it's just the two of you at night, Louise will call him brother again."

He calls me Li Cheng during the day, and "brother" at night...

Li Cheng's lips twitched.

This sounds even stranger... Oh well, let Louise call him "brother" for now, we can always change it later.

Chapter 374 Who really paid for whom?

Let's put the issue of address aside.

The two had just finished lunch and saw that they had plenty of time in the afternoon.

Li Cheng then decided to take advantage of the rare time when no one was home and planned to openly play some kissing and touching games with Louise at the dining table, just to whet his appetite.

Just as he lowered his head to kiss those two delicate, flower-like lips, before he could even stick out his tongue, a silver-haired figure who had gone and returned passed by the restaurant and took in the whole scene.

Fortunately, the person who came was Lavoisier.

She was taken aback when she saw the two kissing and cuddling at the dining table, and then decided to pretend she hadn't seen them and walk past.

Li Cheng naturally lost interest, and since he happened to have something to discuss with her, he put the somewhat resentful Louise in her seat.

"Don't worry, I'm going to figure out a way to resolve our issues completely." He saw through the girl's little thoughts and pinched her cheek. "You don't want to always be sneaking around, do you?"

After leaving an explanation, Li Cheng chased after the pretty figure that had left.

Lavoisier didn't always wear a white lab coat; it was mainly because Lincoln's research made her clothes too dirty. Today, she was wearing a red and black plaid long dress and brown deerskin boots. She had even taken the time to style her hair, which flowed freely down her back, each strand looking incredibly smooth.

Li Cheng quickened his pace, thought for half a second, and then, remembering that there was no one else at home, gently put his arm around the girl's waist.

After all, if possible.

Who wouldn't want to get closer to the person they like?

Lavoisier turned around, looked at Li Cheng who had caught up, and leaned his head against him with a smile.

"Why didn't you continue kissing that little girl?" she asked.

"Cough cough."

Li Cheng coughed awkwardly twice and asked, "Why did you seem so unsurprised just now? Did you already know?"

"How could I not know?"

"Really? I always thought my relationship with my siblings was quite innocent; we'd only hug occasionally at home," Li Cheng tried to explain. "You see, if there's a brother and sister who have a good relationship, aren't they usually very close?"

"Normal siblings?"

Lavoisier curled his lip: "Can't you see the way that little girl looks at you? That's not how a sister looks at her brother—besides, if you go back three generations, are you even related by blood? Only an idiot like Newton wouldn't be able to see that."

The girl didn't hesitate to criticize Newton.

"Alright, since you already know."

Li Cheng said decisively, "Then I'll lay my cards on the table—I started dating Louise, probably around the time in Paris."

"I knew it, you scumbag."

Lavoisier hummed a couple of times, but wasn't really angry: "I bet it was some little girl who just snuggled up to you, acted cute and charming, and you got seduced into cheating? You shameless man!"

"I'm not that casual about it. To be honest, this matter is quite complicated."

Li Cheng didn't want to dwell on this complicated issue any longer, and besides, Lavoisier certainly didn't want to hear how he got together with Louise; he was just using this method to vent his little temper.

"In short, the key issue is that we're facing some problems right now."

He said with a serious expression, "I suspect that now it's not just you, Newton also knows that my relationship with Louise is not normal."

As Li Cheng spoke, he recounted what Annie had let slip that morning, and then added his own speculation, connecting the two events together by referencing Newton's recent outburst.

"Oh."

Faced with such important intelligence, Lavoisier simply nodded calmly: "I already knew that."

Li Cheng: "???"

"You know that too?"

Li Cheng was first puzzled, then annoyed. "Then why didn't you tell me? Did you want to see me kept in the dark?"

"You didn't tell me either, did you?"

Lavoisier countered—she was naturally referring to the relationship between Li Cheng and Louise.

Li Cheng, realizing he was in the wrong, surrendered and said, "Alright, then Newton probably doesn't know about our relationship, right?"

"Of course."

Lavoisier smiled proudly, knowing that she was the only reliable person in the family besides Li Cheng.

Li Cheng then turned his head and gave her a complimentary kiss. The two then performed some oral exercises on the spot. The girl leaned against his chest, her cheeks flushed red from lack of oxygen and excitement. It was worrying that if he let go, she might fall to the ground.

Even so, she still managed to lean close to Li Cheng's ear and said in a slightly effeminate tone, "As for an apology, this alone isn't enough..."

Clearly, kisses and hugs alone were not enough for Miss Lavoisier.

Li Cheng began to look around and realized that after walking for a short while, they were right in front of Lavoisier's room.

What a coincidence!

......

40 minute later.

Feeling quite satisfied, the young girl leaned back in front of the dressing table, her two beautiful red eyes narrowed into slits, displaying an expression as if savoring the afterglow, while Li Cheng used a handkerchief to wipe away the color stains that had accidentally gotten into her long silver hair strand by strand, and then combed it straight again.

Men are still quite fun... Lavoisier thought to himself.

"It feels like I've been prostituted..." Li Cheng thought to himself.

In short, regardless of who actually cheated on whom, Lavoisier is now in a good mood and willing to analyze the problems that Li Cheng, this scumbag, is facing.

"Do you know where your biggest problem lies?" Lavoisier asked, examining him.

"Where is it?" Li Cheng, a struggling student, humbly asked.

"It's because you were too perfect at the beginning," Professor Lavoisier said decisively. "You acted like the perfect boyfriend in front of Newton, being considerate and caring, knowing how to make her happy, treating her incredibly well, and being extremely devoted, making that idiot completely devoted to you."

"Was I really that good? But I don't think I did anything wrong, and I was always bullying her."

Li Cheng had some doubts.

He didn't seem to do anything special, right? Just some everyday interactions...

"Don't tell me what you think, tell me what she thinks."

Lavoisier slapped away someone's groping hand and continued his analysis: "At least from the results, Newton thought so, so when you accidentally revealed your scumbag side, she couldn't accept the reality—on the contrary, look at me, I recognized your scumbag nature early on, so I wasn't too surprised even though I knew you had a relationship with Louise."

"..."

Li Cheng paused for two seconds: "If that's what you're doing, then I'd better act like a scumbag right when I first got together with Newton, and often flirt with other women in front of her?"

"Correct!"

Lavoisier nodded in agreement.

“But I didn’t know I would become a jerk back then!” Li Cheng said, feeling extremely frustrated. “I was a very loyal man at first, okay? The kind of guy who would push away anyone who offered themselves to me.”
