1. YeHua can't think of this idea. Probably he thinks that if mr.zhou doesn't gouge out his eyes, Tianjun won't let go, and sooner or later he will find other ways to hurt mr.zhou. Anyway, he has vowed to be her eyes. We believe that deep down in his heart, he thinks this method can protect Mr. Zhou. Regarding whether he thinks Mr. Su has been wronged, I think maybe he didn't think it was important to entangle this matter at that time. The important thing is to protect Mr. Su from being hurt again.
Secondly, the last question is my guess, and I'm sure I can answer it. YeHua named her Susu because she always wore plain clothes when she first met on a mountain (because she couldn't knit colorful cloth). Su Sukin's speech was just a one-man show.
Third, I will answer this question more accurately. Mo Yuan and Yin Zhong (Yin Zhong or Zhong Yin? ) There must be something about her sister, but this is not the first thing we have to discuss or draw a conclusion. Perhaps, her sister also has some origins with Bai Qian (such as reincarnation). Qi Tang said, the first one is harmony, the second one is harmony with Donghua, the third one is company, and the last one is Mo Yuan. I believe there will be a complete explanation then.
