"Wait for me to come back and wash it. I'll take her home first," said Kevin.

I didn't say anything and Lucy had already reached the door.

She said lightly, "Professor Zuckerberg, no need, I can go back by myself."

Kevin put down the bowl and chopsticks anxiously and the bowl and chopsticks collided violently with the sink. Then Kevin came out.

"Professor Zuckerberg, you just accompany Mrs. Zuckerberg, I'm leaving first, Mrs. Zuckerberg, bye."

"Let him take you. Men nowadays tend to get agitated when they see beautiful girls and you're not safe alone."

Lucy had just put on her shoes. Just about to speak. Kevin had already walked out of the house with his coat.

I stood in front of the French window and no matter how I wiped, it seemed that I couldn't wipe it clean. There would always be a messy mark left.

I went to the balcony and it was already dark outside. I still found that the two pots of flowers that I had carefully cared for had withered.

About five minutes later, Kevin and Lucy came out of the unit door one after the other. Lucy jumped behind Kevin. And Kevin was still holding Lucy's coat in his arms.

"Husband." I called him out.

Kevin opened the car door. I felt his figure pause. He quickly threw Lucy's clothes into the car.

Then he turned his head to look at me.

"Can you please buy two clean rags?"

"Rub?"

"I want something that won't leave marks."

"Got it."

I watched the two people get in the car.

Lucy leaned on the passenger window with both hands and breathed. Then she drew a heart for me.

"Thank you, Mrs. Zuckerberg, for asking Professor Zuckerberg to take me!"

I smiled slightly, turned around and let go of my strength.

The moment the window was closed, the house seemed to have returned to its former tranquility.

I sat on the sofa tiredly. I seemed to still smell the sweet perfume on Lucy's body.

There was Kevin's notebook on the coffee table. His handwriting was very beautiful and next to the vigorous handwriting, there was a very cute student font. The red ballpoint pen was messily drawing on his black lines.

Kevin had profound academic attainments. He could tolerate everything, but he was serious in academics. He would not tolerate any blasphemy. I once crumpled his paper and he scolded me for a long time. Now on this book, after the nonsense.

He patiently wrote it again. I flipped through it again and found that there was a cute illustration drawn with red pen on the first page. The illustration was sunny and energetic, although it was very good.

But Kevin would never allow this to happen. I could even imagine how angry he would be. But the dry notebook looked like it had been drawn for a long time.

There was a noise outside the door and Kevin came in a short while later.

I cleared my head and closed the notebook.

He came over with a plastic bag in his hand. There were two newly bought rags in it.

"What do you want this for?"

"Do the housework."

After a pause, I said again. "I always feel that our home is... messy."

Kevin looked at the tidy living room and said nothing.

Everyone knew that Kevin was a famous cleanliness freak. Wherever he was, it was always spotless. But when I look at my home, I always feel that everything was dirty.

At night, Kevin fell asleep. I couldn't sleep.

I sat on the sofa and stared at the five handprints on the window in a daze. I wiped those five fingerprints all night.

Kevin left in the morning. I heard that he had something to do in the lab.

Before leaving, I called Kevin.

"Can I go with you?"

"We've been together for so long, but I haven't been to your lab yet."

Kevin nodded calmly.

Getting in the car, he fastened my seat belt considerately.

"You didn't take folic acid, did you?"

I shook my head.

Does he really want this child?

The next second, Kevin handed me the bottle of folic acid. I didn't say anything and ate it with water.

The lab was not far from here.

Kevin swiped the access control and took me in.

Contrary to his quiet appearance, Kevin's lab was particularly noisy.

"Professor Zuckerberg! You're here! Have you eaten? I made it myself!"

Lucy stuffed a piece of pastry into Kevin's mouth. She even stood on tiptoe to wipe the corner of Kevin's mouth.

"I don't like sweets, so you don't need to bring me any more."

"Oh."

Kevin didn't eat any sweets, but he didn't spit out the pastry in his mouth.

"Professor Zuckerberg, what do you like..."

Several students poked Lucy. Only then did she notice me behind the door.

"Mrs. Zuckerberg!" she shouted excitedly.

Lucy immediately put her arm around me and enthusiastically led me in.

"Mrs. Zuckerberg, why are you here? Let me help you change clothes? Mrs. Zuckerberg, try the breakfast I made! Professor Zuckerberg is really not lucky."

Other students also surrounded me. They called me "Mrs. Zuckerberg" affectionately.

In the past few years of ordinary life, I didn't even feel that my age had changed. But being with these children, I still felt old. From them, I saw a rare vitality.

"Are you not going to start yet?" Kevin's dull voice was incompatible with their vitality.

But his words were absolutely majestic. One by one, they all pulled their heads together to experiment.

I sat alone in the corner.

Kevin had few students, but they were all outstanding. Among them, Lucy was the dumbest. She had made Kevin look cold several times.

"Let's stop here today."

Everyone lowered their heads, not daring to breathe. They lowered their heads and walked out dejectedly.

"Lucy, you stay."

Hearing this, Lucy turned her head. The sun shone on her bright face, which was really beautiful.

"Professor Zuckerberg..."

"You will do the finishing work later. If the comparison is not successful, you don't have to go back."

Lucy put on her goggles, which were a little crooked. Kevin raised his hand and wanted to help her adjust it twice, but he held back. He had mysophobia.

I walked over and adjusted Lucy's goggles.

Lucy looked at me with a smile. "Thank you, Mrs. Zuckerberg!"

But it was also because of this distraction that Lucy mixed the two chemicals together.

A golden light flashed in front of my eyes and the temperature of the entire laboratory rose. The liquid splashed and stung my forehead. The burning sensation made me groan. The buzz of the explosion lingered in my ears. The whole ear canal was roaring and it took a long time to recover.

When my consciousness faded, I looked at Kevin. He immediately pulled Lucy into his arms. He turned his back to block all the splashes. He was afraid that she would be dirty. The liquid penetrated through the white hexagram and penetrated his skin.

I pressed my forehead and fainted. I knew the erosion of this kind of thing better than anyone else. But Kevin didn't say a word of pain.
