IMO I think you've receded a bit(not much, call it maturing hairline), but because you were born with a poverty hairline and weak temple points, it looks like you're balding. Hair falling out is not a problem(Telogen Effluvium) as long as it grows back healthy. Your hair type is thin and the man bun can cause traction alopecia, which won't help your case.
Unfortunately you're too young for any treatments, so just make sure you keep your scalp healthy and keep an eye for further recession and miniaturization, as it does'n't seem aggressive at all. Don't mistake hairs regrowing for miniaturization, you should be able to tell if it does miniaturize. I can easily tell the difference for mines.
