From the looks of it, the story is going to build up "new" relationships first and then when the relationship with Karl is established again, the woman who made FL break up with him will appear and do the same process and won't believe she lost her memory. But that would probably be the point where she finally has all her memory back.
This is just a prediction

ML was definitely a dirtbag scum who was just full of shit and a sprinkle of humanity. In recent chapters, it's revealed his most trusted people by his side were people he saved and didn't view them as anything less despite their past—and that's how I think it's reasonable that he fell for FL despite their difference in social hierarchy system.
At first he was going to use her because she's pretty, and I don't blame people dropping the manhwa because of it ; I almost did. However, as the plot progresses, he's shown a sense of remorse, as he wouldn't cross the line if she didn't want to (though, he had a moment of two), and wanted her to want him. I think that character progress is worth noting because I believe that is a factor that made FL begin to fall for him. (And he saved her from that bald guy, who knows what could've happened—she's not the sharpest tool in combat).
Nevertheless, there's still a ton of ways that they can do to improve the ML. Starting with, if he really does love her: then throw away the playboy rep.

He's been alone for most of his life (he downright placed curses on people that worked for him so that's his own fault), and she's been treated less of a person because she's a woman.
The intense desire of making her his muse must be stemmed from having no one at his side for the longest time, because she did loved him tremendously.
Now that there's a baby in the picture, she wants to keep it but he doesn't know what the baby will do to her state, but isn't she strong enough? She took that 3rd leg like it's no one's business

The green eyes on Eric suggests that he got possessed by the princess' brother, and the painter's reaction to Charlotte inevitably hints that she's the princess (and also the % that makes her, almost as if remembering, the princess' memories).
I haven't connected any dots for Noah but if I had to guess, he's going to be the hint for what happened to the princess after the painter's death.
This manhwa is so interesting! I love the relationship build up, charlotte's reason to help Dietrich, and Dietrich's need to escape—and his sad backstory. I also love the storyboard, it mixes situations of now and then, without being all over the place or out of place
Man nips
