In my opinion,at your level the study of openings,any opening,will not help you much.
Why not?Because you'll see about 3 to 4 or at best 5 'bookmoves' and then the game takes a unique path.Furthermore you can't yet play well enough to understand the moves advocated in books.All you could do is try to memorise.
Far better to learn opening principles and apply them (more difficult than it sounds!).Like others above I also advise to play classical openings (e4/e5,d4/d5).
You would benefit more from learning better chess.I'll show a few things using a loss of yours onhere.

I checked,it seems the game goes out of book at his 4th move.Rather typical.
After 6 moves you have this position
white to play
and you went 7.f3?
Bad move.some observations:
1.it doesn't help your development (an opening principle)
2.it opens up your king to a check on h4
3.it takes away the best square of your g1 knight (look how unhappy he now is!)
Had you followed opening principles you probably would've found 7.Nf3 which I think is a good move in this position
next move.White to play
8.b4 not really terrible but why kick the knight again?
You need to get your pieces out.8.Ne2 seems perfectly fine to me
10.Bc4?? (now f3 comes to haunt you) Qh4+ CHECK!and the bishop on c4 is lost.
The game is now resignable and so you did soon enough.
However,I would advise to continue playing.Your opponents are equally prone to losing pieces and overlooking mates!
Summary of this game.The opening was a complete success.
after 6 moves you were up a healthy centre pawn.
Yet you lost in 13 moves.Kinda makes a case against opening study,doesn't it?
Some simple practical guidelines
1.Adhere to opening principles,mostly the principle of development.
Don't go pawnsnatching unless you're absolutely certain it's worth it.same goes for chasing pieces.
2.Play with your pieces!!Leave the pawns at rest!!
I know,you see no good move and think moving a pawn can't hurt.Wrong!
And yes,lashing out with your pawns looks aggressive.
But weakening pawnmoves are the cause of many lost games.
3.Whenever it's your turn think about your opponents last move.
Why did he play that?What changed?What new options did it provide for him?
4.Carefully examine all possible checks.A check is the most powerful tactic because you're not allowed to ignore it.
5.Play with your pieces!! 🙂
It is so important I can't stress it enough.
Keep at it with the endgames and add tactical training (if not done already) and you'll become that asset.
