After coming out of Gu Chengkun's study, Gu Mulin followed his mother to the living room downstairs. He had a dark face all the way, and the depression in his eyes was clearly visible.

Gu Mulin's mother is a gentle woman, and she is also very distressed about her only child, which can be said to be very pampered. Seeing that her son was injured, as a mother, she naturally couldn't rest assured. "Son, mom is going to find you a medicine box, you can see that it is already red and swollen."

In fact, this little injury is nothing to Gu Mulin, he has suffered more serious injuries, and he has survived. But his mother cared so much, and Gu Mulin's stiff expression loosened a little. "Mom, I'm fine, this little injury is nothing, you go to rest early."

Unable to resist her son, Gu Mulin's mother had no choice but to return to her room. As he walked, he turned back, his eyes full of pity for his son. After his mother left, Gu Mulin also dragged his tired body back to his room and sat on the sofa alone.

He carefully lifted the clothes covering his arms, and as the clothes were lifted little by little, the sharp pain spread throughout his body little by little. But Gu Mulin didn't snort, he kept gritting his teeth and didn't let himself make any sound. Enduring the pain, Gu Mulin exerted a little force, and his sleeves were lifted up with a "swish".

When the clothes were completely lifted, the wound on Gu Mulin's arm was clearly seen. There were already a few bubbles in the place where the hot tea had been scalded, and the bulging bubbles looked very seeping, but Gu Mulin looked at his injuries without changing his face. As if the top of his arm couldn't hurt himself, his facial expression did not change, making people wonder if he was an arm made of iron.

Gu Mulin stood up and found something like tweezers in the room, broke the bubble with his own hands, and found some medicine to apply on it, but he didn't say a word "pain" from beginning to end. Perhaps because Gu Chengkun has been strict with him since he was a child, Gu Mulin has long learned to live independently, and has also developed an arrogant personality now.

When he was lying on the bed, Gu Mulin couldn't fall asleep after tossing and turning, all that was in his mind was what his father said to him, especially the matter that made him and Luo Bingbing engaged, Luo Bingbing's figure appeared in his mind.

After so many years, Gu Mulin always remembers the first time he met Luo Bingbing. A little girl holding a doll, with a pair of very beautiful big eyes, shouted at herself a little timidly when she saw herself, "Brother." This scene is something Gu Mulin can never forget, because at that time, he already regarded Luo Bingbing as his sister to take care of in the future.

And he did assume his responsibilities as an elder brother, Gu Mulin always protected Luo Bingbing when the two of them were in school, and served as her personal guard. As long as others pray for her, Gu Mulin will immediately help her bully back, which makes Luo Bingbing not afraid of anyone at school, which can be said to be "rampant". So when the two of them went to school, everyone in the school knew that Luo Bingbing had an elder brother named Gu Mulin.

But as the two of them grew older, Luo Bingbing was no longer the little girl who could only cry behind him, but became a girl who could be on her own. At the beginning, Gu Mulin was a little disappointed, after all, the little kid who was following him suddenly grew up and didn't need his protection.

But as time went on, Gu Mulin gradually got used to such an excellent Luo Bingbing. Because he found that Luo Bingbing still had a different side, and there were many shining points that he didn't know before, which could be said to impress him.

What surprised Gu Mulin was that one day when he saw a boy giving Luo Bingbing chocolates and love letters, he felt very angry and very depressed. He knew that such an excellent Luo Bingbing would definitely have suitors, but he didn't expect those suitors to be so direct and rude, and they were so persistent, so he had to admire their perseverance.

Because Luo Bingbing complained to him before, saying that she didn't like those suitors, and even said that she hated those suitors, because she felt that they were not sincere, but for the sake of her classmates, she had to accept those things. So when Gu Mulin saw that she was stopped by those suitors, Gu Mulin rushed up without hesitation and blocked her in front of her, and also fought with those people for this.

This incident caused a sensation in the whole school at that time, because no one thought that Gu Mulin would fight with others, after all, he has always been a good student in the teacher's mouth, and he also looks like he rejects people thousands of miles away on weekdays, and he is very cold. So when the news of his fight spread, the entire campus was shocked, and they all thought that he would fight because he liked Luo Bingbing.

Since then, everyone thinks that the high-ranking Gu Mulin likes a girl named Luo Bingbing. Originally, Gu Mulin scoffed at this statement, because he didn't like to listen to those gossips, and he didn't like others to gossip about him.

But over time, Gu Mulin found that he couldn't distinguish his own heart, and he didn't know if what they said was true or false. Originally, he could confidently say that he treated Luo Bingbing as his own sister, but now he hesitated, and he also had deep doubts about his feelings for Luo Bingbing.

He likes to see Luo Bingbing's eyebrows fluttering in front of him, he likes the way she racks her brains because she solves a math problem, and he likes the way she gets angry because she doesn't wait for her to get out of school. Sometimes she would jump up and down because she gave her a smile, sometimes she would be so excited that she sang because she bought her a cake, and sometimes she would even laugh because of his words.

When Gu Mulin felt that all this was changing, he found that his feelings for Luo Bingbing seemed to have deteriorated, and it was no longer his brother's feelings for his sister, and it was gradually mixed with the love between men and women.

At the beginning, when Gu Mulin found out about this, he was still ashamed of his thoughts, after all, he had always regarded Luo Bingbing as his sister, but later he found that he had long since regarded Luo Bingbing as his sister, but regarded her as a girl full of charm.
