At that time, Xu Tingchuan didn't have much contact with female classmates.

Su Yan and he had grown up together since childhood, and unlike most girls, she didn't blush or stammer when she was around him.

He, Mu Zhi, Pei Yang, and the others always went out together, as did Su Yan. Compared to interacting with other female classmates, she preferred to play and joke around with them.

Later, at some point, Su Yan began to subtly change. She started wearing skirts occasionally and sometimes even wearing a hair clip.

However, he didn't notice that Jia Yue was calling him "Sister Su Yan" repeatedly, making it impossible for him not to pay attention.

Perhaps because he was always focused on his studies, he matured later than others when it came to matters of the heart. It wasn't until Su Yan confessed to him that summer that he realized she liked him.

With a childhood sweetheart relationship as a foundation, and considering that the girls he had the most affection for since he turned twenty were Jia Yue and Su Yan, he assumed that the affection was love, so they naturally got together.

Being together in the same way as being friends before is no different.

However, Su Yan is a very charismatic person, and some of his little habits have changed under her subtle influence.

But that's all there is to it.

During their two and a half years of dating, they probably only spent two or three months together.

Actually, not long after Su Yan arrived in the United States, he realized that his feelings for her were perhaps the kind of feelings one has for a younger sister or for friendship. It was just a kind of confusion arising from childhood friendship that made him misunderstand these feelings.

After he snapped out of his confusion, he wanted to explain things clearly to Su Yan.

But Su Yan was a very sensitive person. She seemed to sense that he wanted to say something to her, so she didn't give him the chance to speak.

Later, during a winter break, Su Yan returned to China, while he continued to stay in the United States.

Just a few days before Christmas, she suddenly made an international call to him and asked him something very strange.

After he finished answering, Su Yan remained silent for a long time before finally saying that she wanted to break up with him.

He then naturally said everything he had always wanted to say to her.

Their breakup was remarkably peaceful and natural, just as it had been when they were about to be together; everything happened with remarkable calm.

After hearing Xu Tingchuan recount the story, Ni Sitian became even more curious: "What question did she ask you?"

Xu Tingchuan lowered his eyes, concealing the ripples in them. He felt it was better not to tell Ni Sitian what was going to happen next, since she and Xiang Zhilan were so close, she would definitely not be able to hold back.

"It's been too long, I've forgotten." Xu Tingchuan shook his head slightly.

Ni Sitian didn't suspect anything, after all, he had been so honest with her, there seemed to be no need for him to hide anything else.

"And then what happened? Where did Su Yan go after you broke up?" She thought that since it was an amicable breakup and they were childhood sweethearts, even if they couldn't be lovers, they should still be friends.

Xu Tingchuan was silent for a long time, then said only, "She went to a very far place."

Ni Sitian keenly sensed that Xu Tingchuan's mood was off, so she pursed her lips and didn't ask any further questions.

She faced him, pulled herself out of the covers, stretched out her arms to hug his waist, and buried her head in his chest.

Xu Tingchuan also hugged her, gently stroking her back, and lowered his head to kiss her forehead.
