So, just looking at the raws and what I can glean from there:
ML sneaks over to her house in the night and they have a long conversation. And they start knocking boots on the regular. Honestly, their relationship is pretty adorable as they’re often shown cuddling.
It seems like he helps her out in reaching out to noble ladies she admires. She, mom, and Cinderella go to some tea party where it looks like she makes headway into fostering friendships.
A woman with glasses appears on the scene, seems the same age as the mom. I think she is there to teach MC how to manage the household and estate in preparation for taking over on her majority.
The betrothal of Wishfold is going forward. She remains besotted, but it seems like he showing signs of being less than sincere, and as such the MC remains concerned.
Sparkly blond with a bob cut is there at the engagement party (?) and seems to show interest in Cinderella. And when he starts talking to MC the ML full on slides down a drape from the 2nd floor balcony to get between then and warn the dude off. Right now I’m thinking sparkly blond is one of the princes.
Next chap MC uses some reverse psychology or something to convince Wishfold to wear a yellow gem necklace, rather than Cinderella’s mother’s. She palms that one and brings it back to Cinderella.
MC and glasses woman go out and talk to some laborers and we finally get a full confrontation between MC and her mom. There’s a lot of reaction shots of the mom through all these chapters showing that she’s displeased whenever MC does anything to forge some independence or strengthen her foundation. After the fight it seems like she basically instructs the servants that “you listen to me, not her” which makes her mother furious. As I’ve said before, a lot of the story seems to be centered around MC beckoning a good family head and wresting control of things away from her mother.
She is invited/summoned to speak to sparkly blond and the dude is 100% enamored with her. Despite barely sharing 3 sentences. (I skipped over a few shots of him sitting ominously in the dark swirling his wine previous to this). Actually there’s something screwy here as there’s a flashback cut of him as a child ‘falling in love’ with an older woman with silver hair, so maybe he met her mom and he’s confused? It seems based purely on her resemblance to the woman he met before. She firmly shuts him down, though he doesn’t want to take no for an answer.
After they come back (ML picks her up from the meeting) it seems like Wishfold may have a new beau. The mom is scowling and clearly resentful that MC’s taken away some of her power. All the girls go to what looks like a house party and once again the MC is nagging them a bit and making sure they’re only dancing with guys she thinks are trustworthy.
That’s it through chapter 13 of the manga.
