Song Yan was indeed provoked by Song Lan this time, she has been too busy to pay attention to Song Lan these days and what was more, most of her scenes were already done. She only needed to finish shooting a few more scenes and after that, she was free to leave the set but Song Lan seemed to have taken her silence for granted she actually went around saying that she was worried that Song Yan might have hooked up with someone which was my she hasn't be coming to the set these days. But the truth was that Song Yan didn't have many scenes to shoot, so why does it matter if she came to the set every day or not?
She was too tired to deal with Song Lan personally and decided to simply cut the last string that was holding Song Lan up.
