WN is still in progress and thus far both Claudia and Yuran are in the running. Claudia shows a lot of interest and makes awkward advances, but Violette has already given up and doesn't notice. Yuran is trying to get closer (and shows a lot of yandere traits tbh) but Violette sees him a lot like a younger brother so he's having trouble. Violette has had moments with both, but was noted by her maid Marin to be especially happy after spending time with Yuran on a not-a-date sort of thing (shortly before her father came in and made her depressed again). There's also the extremely loyal Marin herself who's a bigger character in the WN and is strongly hinted at being in love with Violette, but that's unlikely to go anywhere and only gets mentioned from Marin's PoV.
IMO the story is pushing very strongly towards Yuran, but in all honesty the story hasn't progressed very far at all. More importantly, Violette herself is still very depressed and would need some help before she's in a state where she can properly think about romance. As of the most recent chapters Violette's primary concern is getting amazing grades so her father doesn't have another excuse to bad mouth her when compared to Maryjun who apparently has main character cheat level stats and will get top marks in her grades without too much effort.
