[Hawk Nose] Is it possible to get filler just once?

I've never gotten filler before... Is it possible to get it just once?? My nose bridge is low between my eyes, and I'm trying to correct my beak-shaped nose. Will this work? I heard that filler doesn't completely disappear, but most of it just disappears, so can I expect some to remain in a few years? I would get it done if it made my nose bridge a little higher than it is now... If I get 1cc once, it won't completely spread out like an avatar nose, right? Will it go back to its original state after about 2 years of getting it once? I have so many concerns. ㅠㅠ
