But Han Yuchen's words were a joke, but for Xu's mother, Xu's father, and Xu Zhuxian, it was not a joke, so the family half-falsely and half-really kept this promise and agreement in their hearts, and only after knowing that Xu Zhuxian's brave confession later knew that it was true, not a joke.

However, after laughing, everyone also washed their hands and began to eat, and after eating, Han Yuchen tutored Xu Zhuxian on piano and Chinese as usual.

"Xiaoxian, let's spell your name in pinyin today. ”

"Your name is made up of Xu composed of X and U, and the words ZHU and XIAN Zhuxian, Xu is the second tone, Zhu is the first sound, and Hyun is the second sound. ”

"Oh, oppa, I know, so my name pronounces Xu, Zhu, Xian in Chinese, right?" Xu Zhuxian pronounced his name in Chinese.

"Well, Xiaoxian is so smart. Han Yuchen rubbed Xu Zhuxian's little head.

Han Yuchen looked up at the time, it was time to go to bed, so he urged Xu Zhuxian to go to bed obediently. Even if the two are children, they do not sleep in the same room, and the two people always sleep in separate rooms, and the doors of the two people's rooms face each other.

A few years later, when Han Yuchen was eight years old, he was admitted to Seoul National University with the first place, which made Xu's father and mother happy for a while, and prepared a lot of food for Han Yuchen.

It also made Xu Zhuxian admire Han Yuchen very much, and took Han Yuchen as a learning example and goal. Because of his future plans, Han Woo-jin studied economics and management and film and drama at Seoul National University.

Xu Zhuxian also followed Lin Yun'er's footsteps to elementary school, but because of Han Yuchen's "intensive training", Xu Zhuxian and Lin Yuna went to the same grade.

Seo Joo-hyun is also very happy because she doesn't have to wait another year to meet Lim Yoon-a and can go to junior high school and high school together.

After school that day, Han Yuchen left early first, because he was going to pick up Xu Zhuxian and Lin Yun'er, and after a while, the students came out of the school gate. "Ah, oppa!" the sharp-eyed Seo Joo-hyun saw Han Yuchen at once.

Lin Yun'er also pulled Xu Zhuxian and ran over, Xu Zhuxian suddenly threw herself into Han Yuchen's arms, and Han Yuchen also patted her with a smile.

However, standing here with a boy like Han Yuchen standing out from the crowd naturally caused the girls in the school to look at Han Yuchen quietly and shyly, "So handsome, who is this?"

"I don't know, I haven't seen it. ”

"How can this handsome boy be so familiar with Xu Zhuxian and Lin Yun'er?"

"You heard Xu Zhuxian call him oppa. ”

"Don't you know? This boy's name is Han Yuchen, and he lives in Xu Zhuxian's house, although Xu Zhuxian calls him oppa, but the two of them are not related by blood at all. ”

"I'm so envious, I really want to have such a handsome oppa, how face-saving it is to go out like this. ”

The discussion of the girls naturally reached the ears of Xu Zhuxian and Lin Yun'er, Xu Zhuxian was very happy, in her opinion, her OPPA is of course the most handsome, so many people notice him and like him, which proves that he is really good, and there are many classmates who envy her.

Lin Yun'er is a little arrogant, because no matter how much these girls like it, they can't get close to Han Yuchen's body, and the only ones who can get close to Han Yuchen are herself and Xiaoxian, so you don't have to worry about Han Yuchen being snatched away by others.

Besides, this oppa can't be snatched away by ordinary people. However, there are always exceptions to everything, and there is a girl who walks towards Han Yuchen.

"What's your name?" the girl asked Han Yuchen.

"......" Han Yuchen didn't speak, because he felt that there was no need to answer this girl.

Seeing that Han Yuchen didn't speak, Xu Zhuxian said, "He is my oppa, his name is Han Yuchen." ”

"Xiaoxian!" Han Yuchen shouted and pulled Xu Zhuxian.

"Then Han Yuchenxi, can I be friends with you?"

"No, you can't. Han Yuchen refused mercilessly, and then directly pulled Lin Yun'er and Xu Zhuxian away.

At the community park not far from home, Lin Yun'er stopped, took out sweet potatoes from her schoolbag, and then took a lighter, "Oppa, why don't we bake sweet potatoes here and eat them." ”

Han Yuchen was taken aback, this is true, Lin Yuna used the exam notebook to bake sweet potatoes on the "Strong Heart" program, but this time she was a little younger.

"Yun'er, don't bake it here, it's dangerous. ”

"Yes, Yoon-Oni, Oppa is right. Seo Joo-hyun also echoed Han Yuchen's words.

"Oh, it's okay, don't you want to eat baked sweet potatoes, Xiaoxian?" Lin Yun'er began to tempt Xu Zhuxian.

"I ......" Xu Zhuxian had no resistance to sweet potatoes, and looked at Han Yuchen with some hesitation.

Han Yuchen had no choice but to agree, Han Yuchen watched from the sidelines, so as not to let the fire get out of control, and Lin Yun'er tore up the notebook used for the exam to bake sweet potatoes.

It's just that it didn't last long, the three of them were discovered and taken home directly, the Xu family, Lin's father and Lin's mother, Lin Yunzhen and Xu's father and Xu's mother looked at Han Yuchen, Lin Yun'er and Xu Zhuxian with a serious face.

"Yun'er, how can you play with fire in the community? Do you know that this is dangerous?!" Father Lin said angrily.

"Abba......

"Don't call me, I must teach you a good lesson today!" said Father Lin, and rushed up to give Lin Yun'er a slap.

"Smack!" There was a loud slap, Lin Yun'er didn't feel the pain she imagined, but when she opened her eyes, Han Yuchen was in front of her, his left side of his face was red, and his head was missed.

"Yu Chen......" Father Lin was stunned.

"Uncle Lin, Aunt Lin, and godfather and godmother, this matter is my fault, I proposed to bake sweet potatoes, I'm sorry, I'm willing to admit my mistake. Han Yuchen took all the responsibility on himself.

Seeing that Han Yuchen helped her bear the blame, Lin Yun'er immediately stood up, "No, I proposed to bake sweet potatoes, it's not about oppa, oppa he also stopped me before." ”

"Abba and Mom, Xiaoxian is also at fault. Seo Joo-hyun also stepped forward.

"Uncle Lin, if you want to beat me, hit me, it's me who did OPPA and didn't stop my sisters' bad behavior in time, and I'm willing to be punished. ”

"Yu Chen, don't protect Yun'er, you will spoil her like this. ”

"Uncle Lin, Yun'er is just a momentary playfulness, she will definitely not be like this again in the future, if you want to beat Yun'er, let me replace her. ”

Even if Father Lin was angry again, it would be impossible to hit Han Yuchen, "Yun'er, look at how much your Yuchen oppa protects you!" Father Lin said to Lin Yun'er.

"You've come home with me right now. ”

"Brother Lin, don't be angry, besides, the children didn't make a big fuss, just teach a little lesson. Yu Chen, Xiao Xian, you two will give me a week of piano practice at home, and you are not allowed to go out except for school. Mother Xu said to Han Yuchen and Xu Zhuxian.

"Yes, doll mom (godmother). Han Yuchen and Xu Zhuxian said.
