Mangas Where The Main Couple Shows Each Other A Lot Of Love And Takes The Final Step?

Hello manga readers from all over the world! I apologize for the slightly strange title, but I'm sure you're used to it. I was reading chapter 200 of "My First Girlfriend is Gyaru (Hajimete no Gal)" and I felt angrier than I possibly have in two years. I honestly can't explain my disappointment and anger; every time I remember that nonsense, I get angry.

Because of that I'm currently looking for series like the one in the title. Because I'm serious, every time I remember that episode, I feel like banging my head against the wall.

So if you know of any series like that, please enlighten me. I'm even okay with +18 or cringe-worthy ones, as long as they don't have a bad ending. Of course, it doesn't have to be completed
