Yeah.
It's called 'she's basically seduced the Pope's Son (But not in that way)'.
If you recall, at the start of the series, our heroine ended up in the body of the 'Villian Girl' from an Otome game after a 'perfect' end, where the Protagonist had Max Relationship stats with all of the male otome game love interests, consisting of Second Prince Edward, the Pope's Son, the Prime Minister's Son, and the Knight Captain's Son.
So far, Iris has managed to get one of them out of the orbit of Iris and Prince Edward for sure, and possibly another.
Her brother got yanked up by the scruff by his family and had just what the actual consequences of the sort of things that Yuri and Edward want to do rubbed in his face, plus seeing just how hard Iris works to run their family fief (along with a firm 'Did you ever THINK what your job as Prime Minister would be, Bern? Your duty would be to /tell the king when he's screwing up/' speech from her) back in Chapter 19ish, so he's now actually doing his initial job and keeping an eye on the Second Prince and reporting to his father.
On the other hand, the son of the Knight Captain, Dorsen, got his family massively politically smashed by Ojou-Sama's mom snubbing them socially and his dad was apparently also pissed as hell about how he acted to a lady in public (the indirect bit is where Iris told him 'oh, so this is how a knight acts, forcing a lady to her knees with brute force'), if I recall (Vaguely remember it from the LN at least), so he's been forced out of their social orbit a bit since his spare time is being filled up with additional training.
Back in Chapter 25, Yuri was basically using Edward to bribe the Church into liking her with extra Almsgiving donations, which is probably where Edward's faction got the 'in' they needed with the (honestly pretty corrupt sounding at the moment) Darryl Church to launch their current assault on House Armelia.
