In other words, from the very beginning, he added Ding Ning's WeChat just because he thought Ding Ning was pretty.

He is greedy for beauty, and she is pretty.

That's all.

He didn't think of going any further.

One time, I shared a popular science article about common statistical errors in clinical research on my WeChat Moments, and Ding Ning commented below, saying that there was one thing wrong in it.

Duan Feng was curious: What went wrong?

Then Ding Ning disappeared.

Ten minutes later, Ding Ning sent him a photo on WeChat.

It was her process of calculating on the draft paper, analyzing each specific problem, and listing one, two or three situations for him.

Her handwriting is neat and graceful, with a childish and round feeling, revealing a bit of cuteness.

She typed the whole time, and each time it was a long article of several hundred words.

He waited quietly for her to send one message after another without saying a word.

It can be seen that this girl is simple, stubborn, childish and dull.

He didn't care at all whether the content in the post was correct or not, as he had no use for it. He just forwarded it for his friend.

Who would have thought that after this turn, I would discover such an interesting person like Ding Ning.

He was curious and clicked on Ding Ning's Moments. Her Moments did not have a "visible for only three days" setting, nor did it have any permission settings. Anyone who was her WeChat friend could see it.

He flipped through it out of boredom and found that her circle of friends was just as boring as she was.

They are all the latest research results in related fields, or which journals have been kicked out of the SCI and Chinese Academy of Sciences rankings, or which researchers have been named by the Ministry of Science and Technology for plagiarism.
