i think it's not bcs of him, they addressed this too in the novel where changyu is very reluctant to kill common…
If you see the preview it seems like she went to the battlefield in his stead to keep him safe so of course it was because of his lies that she had to go through all that. She doesn't want to kill but she did for him. Perhaps her little gang followed her to the field and one of them got injured so of course it's Xie Zheng's fault for lying so much
Looking at the previews she should have beat him (Xie Zheng) up pretty hard after all she went through because of his lies. Istg if one of her minions die because of this I'm gonna beat him up myself
Question for novel readers: Is Gongsun not a character in the novel? I am currently in Chapter 29 but he still hasn't been mentioned but the cdrama already had him visited twice by then. Is he not his best friend in the book? π₯²
