Woww.. thanks vm.. I just realize that Tia friend (Entea) and carsein personality somehow match so if you say they will get married, I'm very happy for them and I guess it will be quite a good couple(?) And as long as carsein doesn't get toss aside alone, I'm okay as long as his character get a good ending too..(⊙…⊙ )
jieun spoilers
When Tia was executed and Jieun was shown to have no traits applicable with her status as empress, the entire empire was in chaos. Ruve, in particular, became anxious as he slowly sobered up from the poison duke Zenna kept giving him throughout the years, which is the main cause of his constant mood swings and anger issues. Because of that, he was able to put all the events together and realize duke Zenna was behind everything all along. With the death of Tia, the aristocratic faction (pro-emperor party) weakened while the nobility faction (anti-emperor/duke Zenna's party) rose to power. And because Jieun was pregnant, a new heir would be born therefore it wouldn't be long for Ruve to be made rid of. So when duke Zenna assassinated Ruve, by law, Zenna was able to gain authority as the new ruler because Jieun's child was incapable of doing so. In the end, Zenna killed Jieun along with her child.
Jieun's main goal is to inflict revenge on duke Zenna but we have to keep in mind that when she was offered a second life after dying (like Tia) she basically took the chance right on the spot. Like just when she died and lost her child, she ended up in that dreamlike place and spoke to Vita (holy being) with high adrenaline, an impulsive mindset, and a whole lot of desperation. She made actions based on her emotions (being killed together with her child, being hated for her mistakes, ruve comparing her to tia).
In the end though, she regrets having a second life because she wasn't able to see her family again.
feel free to ask questions if there are things you're curious of. it doesn't have to be questions about jieun.
