Ye Chen wanted Guo Yuyun to go back. He knew that it might be a bit hasty, but to avoid the prolonged nightmares, if the girl Ouyang Yue really couldn't take it anymore and spilled the truth, the consequences would be unimaginable.
He could imagine that if Guo Yuyun knew that there was nothing between him and Ouyang Yue, she would never leave, certainly staying. She and Song Xizhi hadn't wed yet. By then, getting her to leave would be almost harder than ascending to the heavens. With Guo Yuyun's character, she would definitely stay by his side, never abandoning him.
He didn't want that, although he wished for it in his heart. If something were to happen to him, even if it did not harm Yun'er, Song Xizhi would choose to leave. Then, who would accompany this lass in the future? He simply couldn't do that.
