I do feel the story towards the ending is being rushed as well, it started from when she went to the desert. But I’m gonna share my opinions on your questions. House Rimon had to pay extra tax for House of A- (I forgot how to spell it ) as a punishment. The Emperor realized his father was a tyrant and he thought he might as well being one, therefore he didn’t punish them to the point of bloodshed because he didn’t want to repeat the history. The Empress couldn’t do anything for the wedding because it was already legally certified when she found out about the wedding. I assume since Sienna also finally became the only successor of the throne, she gave up since her goal was already fulfilled. And no, Dyan uncle didn’t satisfy with the tax exemption, but he couldn’t do anything since Dyan wasn’t the successor anymore and his child wasn’t divine being. And Fatima probably was Kuhn’s lover in the future/Sienna’s dream, in the future he might meet Fatima and fell in love with her, but since things happened differently in the current timeline, he met Sienna first and fell in love with her instead. And for Fatima and Stud, we don’t need further explanation in the story, we can conclude they were continuing their life in the empire and under Sienna’s protection. And what happened to the greenhouse in the end, does it really matter to you that you’re stressing about it??
Oh I forgot to mention that the Emperor was having second thoughts on how he could punish House of Rimon because the massacre was being orchestrated by the late emperor and House of Rimon was just simply obey his command. But the men who were responsible were already dead, thus he couldn’t punish them
I feel cheated honestly. The story was going so good. Their relationship, lovely. But suddenly it ended without some major key points satisfactorily solved. House Rimon didn't receive appropriate punishment for their wrongdoings not only on the past but in the present as well. WTH happened to the mother? She just let the wedding happen?? And the uncle that was hellbent on revenge was satisfied with a tax exemption? Also, who the hell was Kuhn's lover? Because Fatima wasn't. She mentions Fatima in the future that she died and then mentions his lover as a separate person. Even he tells her he never loved Fatima as she was a person born and raised in the desert. And what happened with Fatima? With Stus? With the greenhouse??? I feel so angry because it was near flawless and then... It ended. Just like that.
