I almost touched the moon

Cheng Che parked his car in front of the Starbucks at Munich Central Station, and soon three young men walked out.

Wen Song rolled down the window and waved to them, smiling and saying, "Hier."

Noticing that they all had backpacks on their backs, Cheng Che also got out of the car, helped them open the trunk, sorted out the ski equipment in the trunk, and said in German a little embarrassedly: "I'm sorry, the trunk was full of ski equipment. Now there should be room for more."

Si Yao immediately said to him in German: "It's okay, thank you Mr. Cheng, we can actually put it on the seat."

Wen Song also got out of the car at that time, took Cheng Che's hand and introduced: "This is my husband, Roche Cheng, he will take us to ETH today."

"So handsome." Nattalie and Samuel exclaimed at the same time.

Wen Song also smiled. Cheng Che knew that she was going to meet her students today, so she wore clothes of the same color as Wen Song. She wore a Dior Dunst black and gray wool coat, a simple white sweater and black casual trousers. She looked casual, but she was actually dressed up carefully. She even styled her hair into a 3:7 side part.

Si Yao also noticed that Wen Song was also wearing a loropiana grey double-breasted wool coat today, paired with a white shirt, black shorts and black mid-heeled boots. He also wore a pair of gold-rimmed square glasses, which made him look more gentle and cool, and also exuded a bit of heroic spirit.

I couldn't help but joked: "How loving! Professor Iseylia and Mr. Cheng are actually wearing couple outfits. Oh my god, we really are like three light bulbs."

"Yes." Nattalie agreed, and then asked, "So Mr. Cheng, did you capture Professor Iseylia with your beauty? Because there are really many people pursuing Professor Iseylia, both men and women. She told us before that she was single, but I didn't expect her to get married suddenly. It was really unexpected. But seeing your appearance, it doesn't seem that surprising."

"Of course not." Wen Song was afraid that Cheng Che might be suspicious, so he held his hand, smiled at him, and then explained, "Roche is a very good person, and his beauty is his least noteworthy advantage. He not only has a good personality and respects others, but he is also very caring.

He has won the gold medal in freestyle skiing slopestyle at two consecutive Winter Olympics, making him the athlete with the most honors in this event so far. In addition, we are visiting Roche's alma mater today. He graduated from the Department of Architecture at ETH."

"Wow..." Nattalie exclaimed, "That's amazing. No wonder Professor Iseylia gave up her singleness."

Samuel also smiled and said, "No wonder Mr. Cheng speaks German so well. At first I thought your native language was also German."

Si Yao also introduced them: "Mr. Cheng is very popular in China and even in Asia. Anyone who likes skiing knows him."

Being complimented by them one after another, Cheng Che felt embarrassed and said to them shyly: "I'm not that good. Iseylia is much better than me. Come on, it's a bit cold here."

Before getting in the car, Wen Song whispered to Cheng Che in Chinese: "Don't mind it, they don't mean any harm, they just don't understand you and they are too surprised. Because I told them every day before that I am single, although I am straight, but unfortunately, no man is worthy of me."

"I know."

Cheng Che smiled, put his arm around her shoulders, and kissed her when no one was paying attention. He said with some pride, "I don't mind at all that in your students' minds, I am just Professor Iseylia's husband. This identity is much harder than being an Olympic champion. During the Winter Olympics, my only competitors were male skiers. Besides, my wife is right. No man is worthy of you except me."

Wen Song couldn't help but kiss him, pinched his face and said, "Yes, my puppy is the best, and the only one I will fall in love with is you."

When getting on the bus, Nattalie sat in the middle seat first. Si Yao suddenly asked her, "Dr. Nattalie, do you mind switching seats with me? Because I want to sit in the middle, closer to the professor's cat."

After saying that, she looked at Cece who was lying on the armrest and smiled sweetly.

"Oh of course no problem." Nattalie immediately changed places with her and said with a smile, "Thank you Artemis, I happen to be a little afraid of cats, although it is really cute."

Upon hearing this, Wen Song immediately took Cece back, held her in his arms and said, "This should be okay, right?"

"It's okay. I'm not particularly scared."

After getting in the car, Si Yao gave them some homemade matcha cookies one by one. Samuel took them and said to her: "Thank you Artemis, this cookie is really delicious. I like the matcha flavor the most."

After hearing his words, Si Yao suddenly became a little shy and whispered, "I'm glad you like it."

Seeing that Si Yao usually looked indifferent to everyone, but now she became a little shy and even at a loss, Wen Song understood what was going on and wanted to help her, so he asked Samuel: "Samuel, this is Artemis' first time to attend a seminar at ETH. Maybe you can share with her the experience of the last particle physics exchange meeting we attended."

"Of course." Samuel immediately said to Si Yao, "If you have any interests or questions, please feel free to ask me."

Si Yao also smiled and looked at Wen Song with some gratitude.

Cheng Che understood everything instantly and observed Samuel through the rearview mirror. He was a typical German handsome guy, with dark brown curly hair, deep eye sockets, a high nose bridge, and clear lines, which added a bit of masculinity to his handsome face.

Unlike many scholars who have a frail look due to lack of exercise, Samuel has a healthy wheat-colored skin, which shows that he must like outdoor sports. He has broad shoulders and wears a white shirt, a black suit, and a black tie, with strong muscles hidden under the suit.

He was tall, a little taller than Cheng Che, at least 1.9 meters. When he spoke, he smiled faintly, revealing confidence and warmth, not greasy at all.

Seeing this, Cheng Che couldn't help but feel sorry for Cheng Xuan. Although Cheng Xuan's features were handsome and he was 183cm tall, compared to Dr. Samuel, he was just a little boy who hadn't grown up. No wonder Si Yao remained unmoved no matter how hard he pursued her.

It was still early when they arrived at ETH, so Wen Song sat in a cafe with the students to chat and discuss. Cheng Che listened for a while and found that they were talking about dark matter.

He said: "I remember that Iseylia published a paper in the December issue of Astronomy and Astrophysics, which challenged the existing dark matter theory based on the study of interstellar rotation curves. The title was "Infinitely Flat Circular Velocity and Baryon Tully-Fisher Relation under Weak Gravitational Lensing."

"How do you know?" Wen Song said in surprise, "When I and the research team from our university observatory and ESO used weak gravitational lensing to determine the gravitational field around galaxies, we found that even at a distance of millions of light years, the galaxy's rotation curve is still close to straight.

This is inconsistent with the existing theory that the rotation curve will be in a downward trend as the distance increases, so I questioned it. Our seminar today is mainly about this. How did you know this? "

Cheng Che smiled and said proudly: "Of course I know, I have carefully studied each of your papers. But there are still many things I don't understand. If Professor Iseylia is free, can you explain it to me?"

"Of course. I'll explain it to you slowly when I get home."

When this paper was published, Wen Song and Cheng Che had not yet reunited, but he could clearly know the journal and date of the paper's publication, and even remembered the title. And she clearly remembered that Cheng Che knew nothing about astrophysics.

It turned out that during the five years they were apart, he had really been silently paying attention to her and supporting her.

If it weren't for the fact that she was surrounded by her students and she had to maintain her dignity as a professor, she would really hug Cheng Che and kiss him hard.

The time soon came to half past one. Wen Song had to prepare for the seminar, and Cheng Che also had to meet with the professor.

Before leaving, Wen Song walked up to him and gently hugged him, whispering in his ear: "If this ends early, would you like to attend our seminar?"

"Is it okay?" Cheng Che asked hesitantly, somewhat surprised, "But I'm not a student of physics."

"Although you are not a student of the Department of Physics, you are Professor Iseylia's husband." Wen Song looked up at him with a confident and doting smile, "As long as you say, Ich bin Ehemann von Professor Iseylia (I am Professor Iseylia's husband), no one will stop you."

"Okay." Cheng Che agreed immediately, and while no one was paying attention, he bent down and kissed her on the side of her face, "Mein Vergnugen." (I'm honored)
