33-year-old Zhang Tian'ai or Crystal Zhang and 32-year-old Xu Kaicheng starred in last year's romance drama Young and Beautiful.
Since filming that in 2019, the two have been rumored to be an item.
Recently, it was also rumored that Guli Nazha, the 30-year-old star of The Dance of the Storm, was a third party in their rumored relationship.
None of them three had officially commented on these rumors until recently.
On Aug 25th, Crystal dropped a massive bombshell on social media to accuse Xu Kaicheng of cheating on her.
Effectively, it confirmed rumors of their relationship and shed light on more.
Crystal shared a seven-and-a-half minute audio recording, with captions, of a conversation she had with Xu Kaicheng.
In it, Xu Kaicheng admitted to hooking up with another woman after having too much to drink at a friend's house.
He said it was all his fault and the whole thing had been tormenting him. At the end of it all, he said he was sorry.
徐开骋表示这都是自己的错，整件事也一直在折磨着他 。最后，他说自己感到很抱歉 。
He also went on a bit spiel to say, among other things, that he could not accept who he is, that he couldn't forgive himself and that only being with her could he not make anymore mistakes.
Shortly after Crystal's post, Guli Nazha took to Weibo to say her piece.
Nazha re-shared Crystals's audio recording and wrote, "Not a third party. I was not one before, I am not one now, and I won't be one in the future!
With everyone accusing me of being a third party, I never dared to believe you're a liar. This recording has allowed me to see what you are exactly!"
Xu Kaicheng also shared a message to clarify and give his side of the story.
In it, he apologizes to everyone (including Crystal and Nazha) and gives a timeline of he and Crystal's relationship during that period.
He explained that Crystal had broken up with him on Dec 16th last year.
He said he was emotionally broken at the time and that's when the "mistake" happened.
He added that he and Crystal reconciled on Dec 24th. Essentially, what he's saying is "We were on a break".
他补充称，自己和张天爱在12月24日又和好了 。说到底，他想表达的是“事发时我们是处于分手状态” 。
Many netizens are not buying what he's selling or they just don't care.
According to 8 Days, even some of his own fans are saying that they can't bring themselves to support him anymore.
而据《8 Days》的报道，甚至连徐开骋的一些粉丝都表示，不会再支持他了 。
