Here is a spoiler page. I think the novel link is on this page https://www.novelupdatesforum.com/threads/a-lady%E2%80%99s-tranquility-%E5%9D%A4%E5%AE%81-story-of-kunning-palace-%E5%AE%81%E5%AE%89%E5%A6%82%E6%A2%A6.154602/
I think Xie Wei and Ning'er will get married in a few episodes:D And although the timeline has not changed completely yet, I think it will change seriously with this. In the opening part, they call Shen Zhi Yi / Princess Le Yang their queen. I think Xie Wei and Ning'er will put this girl on the throne. If that happens, it won't be a rebellious ending for Xie Wei (fingers crossed) By the way, this drama is an adaptation of a book. I wonder if it has English? Or does anyone read it? If only he/she told us the end :D
