Considering the fact that the emperor manipulated the situation so that they would have sex with each other and continued to manipulate and lie to her up until she ran, I can see why she villainized him. The emperor also doesnt care about her choice at all and continues to pursue after she's shown that he's afraid of her. The man isn't a good guy

... He didn’t manipulate the situation so they would have sex with each other. Where did you read that? She came on to him and he happened to already have feelings for her at the time, so he went along with it.
Also, they lied to each other. It just so happens that the emperor knew she was lying, so he had the upper hand the whole time. Especially with the imperial/streets doctor sharing her medical information with the emperor, which actually annoyed me because that shxt should be confidential.
I also felt super bad for her when it was confirmed that he knew everything because she’d been stressed AF, trying to hide this from him. I wonder though, if she’d confided in dream-Kyle and told him about how stressful it was for her, if the emperor would’ve come forward and come clean to her at that moment.

No. That’s not the impression she’s under at all.
She ran because she was scared for her life—based off rumors she’d heard along with the emperor’s inability to not come across as the villain he’s been portrayed to be.
She ran because she felt hurt and betrayed once she found out that dream-Kyle whom she started to have feelings for, was the same person as the emperor she knows nothing about.
She ran because he put his own desire to see them get together before her own wants and desires, ignoring hers as if they didn’t matter. That’s why she ran. Not for any other reason.

Minor spoiler ahead!!
in her defense tho she tried to confide with him abt the baby by discreetly asking but all she got as an answer was he'll hurt them coz they will sure be lying, any mother will be scared after hearing that too. The way he confronted her too abt the baby was pretty bad and coz he doesn't know how to show affection bcoz of his past ┑( ̄Д  ̄)┍ in the end it all boils down to lack of communication, misjudgement, and all in all, a very very fast paced 'romance'.
still THE ENDING SCENE AT THE PREVIOUS PAGE WAS PRETTY FUCKING HILARIOUS HAHAHAHHAHAHA. they'll get through it, he's a good dad and she's a good mom believe me, they just need a little push to break off the chains of the past to go all lovey dovey withoit any worries. mwehheheheh
Hahahahahha I’m sorry, but that entire exchange was hilarious AF to me.
People whining about how disgusting or wtvr word they can find to show they dislike these kids meeting their father might have a point because the emperor was definitely acting like a kid, but I still enjoyed that exchange. I guess seeing the raws in advance might also be the reason why I’m not at all pissed at him, but knowing myself, I would’ve still cracked up.
Meanwhile I’m actually disappointed in our FL vilifying him to their kids like that. I don’t know what it’s about, but there’s just something about that, that I’ve always found wrong. Like when parents divorced and one of them keeps custody of the kids and they spend their time talking shxt about their father or mother to the point where the kids can’t have their own thoughts and judgement in the matter. It’s just not something you should be allowed to do. It’s like burning bridges that you didn’t know were even there, so when the two parties get to that place, they realize: “oh so there was a bridge there, but the path for us to meet no longer exists.” In such circumstances you either give up or you take a crazy detour.
Anyway, If kids are meant to find out that their father is a villain, then they’ll find out on their own. Burning bridges like that is petty AF.
