I am new to anime and i just finished 3 anime 1 clannad and clannad after story and Itazura na Kiss i love the plot how they both start in highschool and continue through their lives if you know of any anime like that i would love if you would share.
in the animation of Nisekoi there isn't really anything happening, but the manga is very promising though. Golden time is exactly what you're looking for, but they don't start a family. In Chuunibyou Demo Koi Ga Shitai they don't even go to college and Kaichou wa maid-sama is a bit like Nisekoi: they just become a couple in the animation but in the manga they get married. Sorry for the correction. I don't know of any other anime like that than those you've already watched.
