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

There was also a ticket in the invitation, but the place was not the humble African country he had just returned to, but a famous city in Europe.

Gu Chenglan did not hide the meaning of the whereabouts, he showed the ticket to suno.

Suno was stunned and didn't know what to say. She has been doing psychological construction, always feel that she can bear to leave.

However, the date on the ticket let suno clearly realize that the difference is already in front of him.

"Can't wait until your birthday?" Suno gently pinched Gu Chenglan's fingers, as if afraid of crushing him with force: "your 20th birthday."

"Sorry, Xiao Nuo..." Gu Chenglan hugs suno and prints a kiss on her forehead.

"Then I can't give it to you." Suno gently choked: "I had a class that day."

"Good. I'll call you when I get back. " Gu Chenglan's heart twisted like a twist of pain.

"Can you write? International calls are very expensive. " Suno asked, quietly and carefully.

"I can write. I'll call you when I'm free. " Gu Chenglan said softly, "but I may not receive your reply. I may not stay in the same place for a long time."

"Well, is there any danger?" Suno raised his head and asked earnestly.

"No. Is very tired, very tired, the kind of tired that breaks through the human body limit Gu Chenglan also raised his head and faced the sky. Because he didn't dare to look into suno's eyes.

"I'm on holiday. Can I see you? Or come back to see us when you're on vacation? "

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

Suno was silent. In fact, the difference she experienced in her previous life is more frightening and helpless than this one.

But fortunately, her life was totally different in this life. Mother is very good, brother is very good, everything is OK at home.

Suno can let himself go and wait without any distractions, even for another 20 or 30 years.

"Su xiaonuo." When Gu Chenglan looked down at suno again, his eyes were a little red, "don't wait for me. Because when I come back, we won't be where we are. We all keep moving forward and give each other the best when we meet again

"Well, I know." Suno buried his head in Gu Chenglan's arms and finally couldn't stop crying.

On the day when Gu Chenglan left, it was cloudy, but there was no rain. The black clouds in the sky seemed to be pressing down, and suno was cold all over.

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

She didn't know which direction Gu Chenglan's plane was flying away from. She only felt that the air pressure in the sky was too low, which made the heart ache.

Wait. Low pressure? thunderstorm?

Suno suddenly put down the water cup in his hand, rushed to the window, looked up at the big group of dark clouds in the sky, and suddenly thought of something.

"Suno, why are you going?" Zheng Mingming saw suno running down from the second floor and rushed out of the door.

Zheng Mingming rushed out: "it's going to rain, take an umbrella."

"It's OK. I'll take a taxi." Suno returned and rushed to the road, reached out and stopped a taxi: "to the airport."
