Gu Zechuan was born in a well-to-do middle-class family, a government official in City B, and his mother was a manager of a construction company. In the year of the college entrance examination, his father hoped that his son would inherit his father's business, be admitted to a university of political science and law, and enter politics like himself in the future. However, children who have not been cared for by their parents since childhood are always rebellious, so he did not listen to his father's orders and enrolled in a medical university and became a surgeon. seems to be elegant, but in fact, he also has an unruly gene in his bones, which is why he can become good friends with Zhan Yiyan, who grew up in an orphanage. They also do not succumb to the eyes of the world, they seem gorgeous in appearance but have lonely souls in the middle of the night. Gu Zechuan later thought that if it weren't for the appearance of this girl named Mu Qingning, he and Zhan Yiyan might be good buddies and brothers for life. However, the rotation of the gears of fate is not controlled by manpower, and some people may be destined to encounter it no matter how they dodge, at a fixed time and in a fixed place, just as he met Mu Qingning. Mu Qingning's appearance is like a ray of sunshine in winter, maybe they are all greedy for warmth, and they all want to hold on to it firmly, and then never let go.

Gu Zechuan usually likes to go to the gym regularly to exercise, but in recent days, he has given up the gym he usually patronizes, and traveled thousands of miles to the stadium of D University to run, telling himself that he wants to change the sports environment, what is the real reason, he told himself not to think about it, let alone to dig deeper.

Mu Qingning ran around, stopped to rest, and inadvertently looked up and saw a familiar figure in the crowd in the middle of the circular runway, a bit like ......

"Brother Sawakawa, it's really you. Mu Qingning said in surprise.

"If you can come for a run, can't I also come to exercise?" Gu Zechuan asked her with a smile, with a flash of surprise and excitement in his eyes.

"I'm normal, but if you come here to exercise on purpose, it's too reluctant, isn't there a gym near your hospital?" Mu Qingning looked at him in confusion, this kind of abnormal human thinking really couldn't read.

"Little fool, do you really think I'm here to run on purpose, I just came here in the afternoon to do some errands, and then I came here to visit in the evening, after all, this is also a century-old school, visit. Gu Zechuan gently knocked Mu Qingning's head with his hand, with a really innocent expression. However, how many days he has been staying here for someone, only he knows.

"Oh, that's it. Mu Qingning suddenly realized.

"How many laps have you run?"

"One round!"

"You don't want to run after only one lap? Well, let's play a game, how about it?"

"What game?"

"We race and run, a lap is a cycle, whoever runs first to the finish line can ask the other party a question, the other party must tell the truth, not lie. ”

"Yes, but ...... Hehe, you have to make me half a circle every time, I'm a girl, you have to let me show your gentlemanly demeanor, you should not mind if your physical strength is so good. ”

“…… , Miss Mu, why didn't you say that you were waiting for me at the finish line. Gu Zechuan looked helpless, but still accepted this "unequal treaty".

The first round ended with Mu Qingning's victory.

"Now prepare your mind, I'm going to ask a question!" Mu Qingning smiled evilly. Gu Zechuan who watched it was furious in his heart, this little girl didn't look at her temperament and quiet, in fact, there was definitely a little devil living in her heart.
