On a sunny weekend, Zhang Lurang and Su Zaizai went to the aquarium to play together.The aquarium is full of all kinds of wonderful marine life, making people feel like they are in a mysterious underwater world.However, something unexpected happened during their trip.

As they were walking through the corridors of the aquarium, they discovered a lost little boy named Doudou.Seeing Doudou's panic, Zhang Lurang and Su Zaizai decided to help him find the teacher without hesitation.After some twists and turns, they finally found Doudou's teacher and successfully sent Doudou back to the teacher.In order to thank them for their help, the teacher gave them both a beautiful pendant.

Su Zaizai happily handed another pendant to Zhang Lurang. Although Zhang Lurang didn't say anything, he was very happy in his heart.This pendant became a bond between them because it was the only thing they had in common besides their school uniforms.

At school, classmates began to talk about the end of the world.Some students are convinced of this, while others are skeptical.However, these discussions did not affect Zhang Lurang and Su Zaizai's studies.They study hard together in the library to prepare for the upcoming math competition.

While studying, Su Zaizai couldn't help asking Zhang Lurang an interesting question: What would he do if the end of the world really happened?The two chatted happily, as if the whole world had been forgotten by them.

The day of the mathematics competition finally arrived, and both Zhang Lurang and Su Zaizai were extremely excited.They took a car to the competition venue together, but on the way, Su Zaizai fell asleep because of being too nervous.When she woke up, she had missed the departure time, and the two of them could only rush to the bus station.

On the bus, Zhang Lurang kept calling Su Zaizai, worried that she would miss the game.Fortunately, they eventually made it to the competition location in time.Su Zaizai was assigned to a room where there was a girl named Xia Ning who was participating in the competition.After the two greeted each other, Xia Ning showed a strong interest in Zhang Lurang.

In the evening, Zhang Lurang was still working hard on practicing questions, but Su Zaizai was a little uneasy because of Xia Ning's appearance.She couldn't help but began to doubt the relationship between herself and Zhang Lurang.However, Zhang Lurang has been silently supporting her, giving her strength and confidence in his own way.

After the exam, Zhang Lurang waited at the door for Su Zaizai to come out.When Xia Ning took the initiative to invite him to the snack street, he refused without hesitation.Because he knew that Su Zaizai needed him and he needed to be by her side.When he saw Su Zaizai frustrated because she was in a bad mood, he took out her favorite jelly to comfort her.This move moved Su Zaizai deeply. She understood that Zhang Lurang was her most solid support.

In the next few days, Zhang Lurang and Su Zai went to many places together and enjoyed each other's company.They rode the ropeway together, admired the scenery, and enjoyed each other's company.In the process, their relationship became deeper and deeper.

However, when Su Zaizai saw Zhang Lurang chatting with Xia Ning again, she couldn't help feeling a little uncomfortable.She was worried that Zhang Lurang would be snatched away by Xia Ning, and that their relationship would be affected.However, Zhang Lurang told her with practical actions that their relationship was indestructible.He gave something to Su Zaizai before returning to his room.This move made Su Zaizai very happy. She knew that Zhang Lurang really liked her.

Xia Ning saw the same pendant worn by Su Zaizai and Zhang Lurang and mistakenly thought they were in love.However, Su Zaizai quickly denied this.She knew that the relationship between her and Zhang Lurang was not that simple.She needs time to slowly understand Zhang Lurang's feelings for her and slowly understand his inner world.

In this process, Su Zaizai also understood a truth: love is not achieved overnight, it requires time and effort to cultivate.She is willing to use her sincerity and courage to get close to Zhang Lurang and strive for their happiness.

In this way, Zhang Lurang and Su Zaizai's experiences in the aquarium and mathematics competition became eternal memories in their hearts.They experienced laughter and tears together and spent unforgettable times together.Their feelings have also been sublimated and tempered through these experiences, becoming stronger and deeper.They believe that as long as they join hands with each other, the future will be better.
