Why does Weibo's celebrity relationship always make fun of Sister Bang and Ma Jianguo? What's the relationship between courier Daniel Wu and muscular man?

Muscle man and courier Daniel Wu are a pair of cp, please pay attention to Daniel Wu courier Weibo in daily life. Yan Yan shared her daily life with the muscular man on Weibo, and then slowly addressed the muscular man as "he" and sent two Weibo words: "He said he would break up without help" and "He finally said it", which should mean establishing a relationship.
