Why did the city camp Mitty Cray dissolve?

In the TV series City Camp, Xing Kelei broke up because of misunderstanding.

Xing Kelei didn't accept Mika's advice because of his injury, and he was even a little anxious for success. In this way, two people had a deep misunderstanding. Mika was just busy at work, and Xing Kelei had to go out on a mission, so they didn't contact each other again.

Mika found herself infected with an infectious disease after working and living for a long time, and was immediately isolated. The isolated Mika thought of Xing Kelei. Seeing that he didn't have a short message, let alone a word of comfort, instantly caused a deep misunderstanding between the two people. Later, after Mika finally overcame the disease and went out, Xing Kelei did not know that Mika was isolated. It can be said that the misunderstanding has deepened.

In this way, two people experienced a lot of ups and downs, which could have been good, but when they met again, they broke up and said they didn't love each other.

Xing Kelei was attracted to Mimi for the first time.

After the incident, Xing Kelei also received a thank-you card from Mimi, which he kept. It was not until two years later that he met Mimi who came from the hospital to attend the training. He took out the card from the drawer, recalled the scene and smiled unconsciously.
