Xia Xibei didn't know what kind of trouble Dong Shulan had started, they had no relationship once they got the severance letter.
As long as they did not come to provoke her, she would not have a problem with them.
As for Meng Sushan. The girl was not her concern. They didn't even have a relationship.
After the birthday party, Xia Xibei had to shoot a music video and also record a new song, which left her very busy.
The few songs that came out before still needed MVs.
A MV had several different formats.
One kind was made by the singer herself, who did all the singing, dancing, and acting.
The other kind was to get other actors to shoot the song as a story, in which the singer only made a "cameo."
Xia Xibei chose to get other people to do the shooting.
This was also a chance for others to work and get exposure.
