What were the interpersonal relationships of each member of F(x)? Which artists did they have better relationships with?

The F(x) group referred to the Korean group, Felix, consisting of Jang Hyun Seong, Kim Joonseo, Lee Ki-Gwang, Choe Seong-Chol, Yoo Chimin, and Zhong Chenle. After their debut, Felix experienced a period of low ebb, but as time passed, the relationship between the members gradually became harmonious. Zhang Xiansheng and the members knew each other before they debuted. He worked as a dance coach in the company, so he established a deep friendship with the members. He and Li Qiguang had the closest relationship. The two of them had once participated in the variety show "We're Married" together. In addition, his relationship with the other members was relatively harmonious, but his relationship with Kim Junsu and Cui Seongchul was relatively poor. Kim Junsu had a relatively good relationship with the members. He worked as a music producer in the company and had collaborated with the members on many musical works. He and Li Qiguang had a close relationship. They had once participated in the variety show "We're Married" together. Li Qiguang also had a good relationship with the members. He worked as a singer and actor in the company and worked with the members on many musical works. His relationship with Zhang Xiansheng was average, but he had a good relationship with the other members. Cui Shengche's relationship with the members was relatively distant. He worked as a host and guest in the company and had fewer collaborations with other members. Liu Zhimin's relationship with the members was relatively ordinary. He worked as a dancer and a choreographer in the company and worked with the members less often. Zhong Chenle had a good relationship with the members. He worked as a singer and actor in the company and had collaborated with the members on many musical works. The relationship between the members of the Felix team was relatively harmonious, but the specific artists with whom they had a better relationship still needed to be analyzed according to the specific situation.
