I just read the novel and skipped a few parts(because it was too long and im a med student who still have online classes to attend to) but I was able to grasp the whole plot. To reveal what will happen to him will spoil the story so much imo when we haven’t been introduced to key characters yet. The only hint I could give you is this: He won’t end up with Mielle.
He practically his sister servant!
He did fall in love with Aria but since his sister forbidden him to be close to a "prostitute child" he had had to cut his friendship with her & get engaged with Mielle!
Also the sister, "princess" Isis, is practically the boss of Mielle & she was to be the prince fiancée so she practically the second villainess of the serie with Mielle!

In my opinion, I find Oscar is the most pitiful character in this story. Her sister (Mielle benefactor) are the one who force him to engage with Mielle. Mielle also always asked for his sister to help her when he find Oscar seem to has feeling for Aria.
For Oscar ending, the prince (Asher) who at that time already married to Aria has decided to strip his noble status because his family rebellion to royal family. His father and sister start it, they treat him like nothing. Mostly her sister doing, she want to marry Asher. Also, Asher know Oscar like Aria, that add the reason why he didn't like Oscar.
I tell you, the story is really straight forward expect Aria for background which seem not suitable to marry the prince (some people disagree I guess) since her mother is actually commoner & ex-prostitute. But later on author will reveal who is Aria actual father and it settle her background issue. I like that Asher & Aria relationship is not bashful and really straightforward, they know what they want, so it's really refreshing.
Back to Oscar, his character don't have any meaning and impact, he serve as his sister pawn and have been force to engage with Mielle. Only for Aria used in order to make Mielle jealous, since Mielle is really in love with him (not really... hahah). I actually forgot the reason why his sister want Oscar to marry Mielle.
Ahh.. it will be lengthy if I don't stop now. I'm very chatty and my story line is a mess. Sorry for my wrong grammar, it's not my first language.
Let me know it you want to know anything else. I'm eager to share actually

not really... he didn't get anything at the end... but he did have better ending compare to anyone else.. but maybe we can consider it is a nice ending since he still didn't die at least.. hohoho - as I said, he is just pitiful... no back bone whatsoever, he promise to give cooperation with the authority and to tell them about his family rebellion, that's why the prince just strip his nobility not sure if he was kick out from the kingdom too...

I think Oscar do something after Aria back to her room during Mielle birthday party.. He go to find Aria and did something which make Aria realize that Oscar really like her and from then on she stop using him. Since she know Oscar like her and that will effect Mielle or something, so she decide not to use Oscar anymore.. Because I pretty sure that Aria stop using him after she satisfy with Oscar reaction/ or somehting....
SPOILERS FOR ANYONE WHO WANTS TO KNOW WHO ARIA WILL END UP WITH!!!!

She will end up with the prince!!! (He will think she is Miellé at first but then after some while he will realize he mixed them up because of the bad rumors about Aria and they will fall in love with each other) he won’t tell her his identity at first. (He is the blue haired guy who asked her about how she knew that the casino will go bankrupt and that the owner will run away and was impressed by her!!!!) THEY ARE SO CUTE TOGETHER AND HE REALLY CARES ABOUT HER
