Chu Peihan's company admitted that a man had splashed sulfuric acid on Chu Peihan in the parking lot of the block that she lived in. Because Chu Peihan reacted quickly by covering her face with her arm, her face wasn't injured, but her arm was.
She was seriously injured, but Gu Ning's medicine helped her a lot. She was much better now, but it couldn't change the fact that Wu Yiwei broke the law.
Afterwards, the man said that it was Wu Yiwei who paid him to do that and Wu Yiwei confessed as well. Therefore, they sued her.
Because Colaine was very famous in their country and its great effect was well known to people, the explanation didn't arouse doubts.
Why did Wu Yiwei do that to Chu Peihan? Chu Peihan's company didn't elaborate on that.
People guessed whether they had conflict during the filming. After all, Wu Yiwei met Chu Peihan in the crew of the TV show.
