In chapter 144 I believe they already told their grandparents since the title of the chapter was "What is your relationship. Then in chapter 145, the grandparents are shocked, in the first panel, moving forward was a lot of questions from the grandparents, then suddenly the grandpa of jinyao got angry.That's were the preview ends. (I can't understand chinese so i rely on the illustration), then when I translated the title of the chapter, it was " 145: Disagree" I think Jinyao's grandpa doesn't allow there relationship. Though in the past chapters the great-grandfather didn't have an issue with Jinyao and Yi Yun, maybe he will help them.
