For me the twins, the plot and characters are all good but I also get why they get hate... I mean the drama is all good... until I remember the twins are reincarnated 19+ year olds like yeah their traumatizing first 5 years gave them an emotional set back but I think they've had enough breathing room and it would have been nice for them to get themselves together and not get so emotionally invested in every aspect of the royal family, especially if their goal is to get out of there.
I think the their characters revolve around them embracing and being acknowledged as legit prince and princess a little too much and it keeps going back and forth with their hearts wavering and it's limits their character development

In 89 chapters so much plot has accumulated in comparison to the other daughter of en Emperor manwha's 200+ chapters and there is 4 year difference between the two too.

It starts out really good but after a hundred some chapters it's just full...

How did he not see her!!!?!!! Σ(╯°Д °;)╯╧╧
.... Was my first reaction but it makes sense, he was completely fixated on saving her with what he knew that he had no time to look around at other possibility... Which makes it sadder. This is the first time I truly hate an emperor, most non MC/ML emperors annoy me or are just dumb but this one is dumb, annoying and vile
Rich girl has fallen, whether in love or obsessed woth him we shall see. She feels guilty so I guess she isn't a shameless rich girl, hopefully he doesn't get too involved with them tho, I wanna see him awkwardly interact in society more hehe
