Why are Joseph Cheng, Ariel Lin and He Xiangjun a triangle?

Because he had an affair when he co-produced Love Contract, and then because he had an affair with a mischievous kiss, Xiaomei (He) and Joseph Cheng were also good friends, so everyone said it was a triangle relationship ~

However, this should be an anecdote deliberately created by the brokerage company or the crew to promote the new film and increase the exposure! ~
