Iirc from the spoiler the ardal 30 years ago was his mother., so what happened might be, that house bagot ( his family that persillion killed) faked their child as an ardal and became empress even with the lies., now for whatever reason if the emperor was aware or not, they made him and persillion's mother meet and do the deed, so a royal blood and ardal blood would actually be produced, which is currently persillion
This author is good at making their character like real, you know people changes all the time and whatnot, they aren't bound to stay the same in regards to the situation at hand, but of course it's hard to tell a story like that, as stories has certain need of a character to further the plot., But the author succeeded with flying colors.,
The author's other story, they kinda hate uke from vol 2 which is I guess understandable, but then again, the character was staying true, and rather than act to save their relationship as priority, the uke acted like normal people in which they weren't the only people in this whole world, and what matters was the situation at hand that time (he accidentally burned a seme rival he ended up staying as a housekeeper for him for a few days) so he did the right thing., Like it's easier to choose a path for the plot but the characters are written so well almost like they were living and hard carrying the plot
It's quite amazing how much plot unfolded within 43 chapters tho., usually other manhwas will have this much at chapter 120 something., and I like how the author is trying to explain why each of their character is like that, I also think they're trying to convey a message with their writing as it already strike thrice., it's interesting, even misunderstanding events are well rounded before it got overboard but not feeling empty after it was solved because they go to the next plot unfolded xD within 43 chapters xD
Dan stayed the night with granny after having that bad dream because he was afraid it might happen., he wasn't the type of person to care for himself, (rather., people who put others before themselves) so I guess that's where jaekyung appears back in his life, another soul Dan needs to take care of, so he can so stride unto new chapter of living another day., ( Dan seems like the type of person to devote their life for someone else and view that as "living" nothing wrong with that, it's just he needs literally 'someone else' to function or to feel that he has a purpose in life so he feel alive)
