Ah, I was afraid of that. Figured I'd pitch it anyways in the hope that there was enough difference.

Alllright, so a redesign is in order.
So what if I list some of the aspects I'd like my character to have? See which can be changed, which ought to be dropped altogether, then I'll go off and try to cook up something more unique?
(Also how do you make bulletin lists? I saw you doing that on some previous posts, seems useful for this sort of thing, but it's been forever since I've used the site and it doesn't seem to be in the formatting shorthand.)

---Gonna put a border here to mark where the listed aspects begin---

So to start with aspects I have in mind, generally I imagine a talented scion from a (possibly influential) noble house. I wanted him to be talented in something that's useful in combat, though to be honest I wouldn't mind changing the specifics to something distinct from other characters.

My first thought as to how he would interact with the heroine is to be initially aloof, being more absorbed in his own interests, unless she manages to catch his eye. Possible examples being good at something he's interested in (I imagined him as proud and competitive), discussing a subject of his interest, a chance encounter at a formal dance (he likes that ballroom aesthetic)...
The reason for the initial lack of interest is a mild touch of eccentricity, fixation on his own fancies.
I may have jumped the gun in describing him as a "star student" earlier. He would perform well when engaged in something that can hold his interest, but may have trouble keeping focus otherwise.
If you're wondering where all these remarks about 'pride' and 'eccentricity' were in my initial post, I cut them out to try and focus on the broad strokes. I'm trying to avoid just writing the whole character before the rough edges have been sanded.
Anyways, I don't know whether or not any of that overlaps with someone else, but I'm not especially married to most of it if you want me to change those concepts.

Rivalry with the heroine in the game was an idea that came about as a consequence of practicing swordsmanship and being competitive. Honestly not critical, can cut this out easily if need be.

Last but probably not least of the things I can think of at the moment, having the potential to fall for the villainess. If such a girl exists, anyways. I uh... I actually quite like this idea. So if it doesn't overlap with anyone else's character, I'd like to keep it.
As for the consequences of such a thing happening, I generally thought it ought to result in the becoming a problem for the heroine. My first instinct was for him to become a dangerous boss, but I can definitely see how that overlaps a lot, and honestly I'm thinking perhaps to leave it at something like "he has a chance to fall in love with the villainess."
