Before the long National Day holiday, Gu Chenglan received an invitation letter from abroad.

There was a ticket in the invitation letter, but the location was not the humble African country he had just returned, but a well-known city in Europe.

Gu Chenglan didn't mean to conceal his whereabouts, he showed the ticket to Sunuo generously.

Su Nuo was startled and didn't know what to say.She has been doing psychological construction and has always felt that she can bear parting.

But the date on the ticket made Suno clearly realize that the difference was already in sight.

"Can't you wait until your birthday is over?" Su Nuo gently squeezed Gu Chenglan's fingers, as if he was afraid of squeezing him apart with force: "Your 20th birthday."

"I'm sorry, Xiao Nuo..." Gu Chenglan hugged Suno and pressed a kiss on her forehead.

"Then I can't send you off." Su Nuo choked softly: "I have class that day."

"Okay. I'll call you when I come back." Gu Chenglan's heart was twisted and hurt like a twist.

"Will you write letters? International long distance calls are expensive." Suno asked in a low voice and cautiously.

"I will write. I will call you if I have time." Gu Chenglan said softly, "It's just that I may not receive your reply, and I may not stay in the same place for a long time."

"Then, is there any danger?" Suno raised his head and asked seriously.

"No. It's very tired, very tired, the kind of tired that breaks the limit of the human body." Gu Chenglan also raised his head and faced the sky.Because he dared not look into Suno's eyes.

"I'm on holiday, can I see you? Or you come back to see us after the holiday?"

"I'm afraid not." Gu Chenglan sighed: "Closed training, four years is the shortest cycle. If I do my best, I will come back."

Su Nuo was silent.In fact, the difference she experienced in her previous life was more scary and helpless than this time.

But fortunately, her life is completely different in this life.My mother is fine, my brother is fine, and everything at home is fine.

Suno can let himself wait without distraction, even if he will be on board for another twenty or thirty years.

"Student Su Xiaonuo." When Gu Chenglan lowered his head and looked at Su Nuo, his eyes were a little red, "Don't wait for me. Because when I come back, we won't be where we are. We will all move forward and meet again. I can give each other the best."

"Well, I know." Su Nuo buried her head in Gu Chenglan's arms, and finally couldn't help crying.

The day Gu Chenglan left was very cloudy, but there was no rain.The black clouds in the sky seemed to be pressed down, and Su Nuo was chilling.

Suno did not go to school either, but nestled on the second floor of Zheng Mingming's small supermarket, holding a glass of cold water and staring out the window blankly.

She didn't know which direction the plane Gu Chenglan was on was flying away from, she just felt that the air pressure in the sky was too low, and the boring people felt pain.

Wait, the air pressure is low?thunderstorm?

Su Nuo suddenly put down the water glass in his hand, rushed to the window and looked up at the big black clouds in the sky, suddenly thinking of something.

"Su Nuo, why are you going?" Zheng Mingming saw Su Nuo running down the second floor quickly and rushed out the door.

Zheng Mingming hurriedly chased it out: "It's going to rain, bring an umbrella."

"It's okay, I'll take a taxi." Su Nuo rushed towards the road with a reply, and stopped a taxi: "Go to the airport."
