The only reason why 1st girl meme isn't just a meme is because 11s are base insects who don't like having their society change, hierarchy disputed, or boat shaken.
As such, J-series always reinforce tropes. First girl wins like 99.9% of the time. Love Hina, Onegai sensei, Ai Yori, Nisekoi, Toradora, Clannad(anime), or whatever non-romance that has romance elements. Japs are autists who don't get bored of seeing first girl win every time.
