I find it more frustrating when guy doesn't end up choosing anyone, like Nisekoi and at least a hundred more harems / romances. Luckily there are a few that end up with marriage.
There is a harem that ends with marriage. Although it's between a guy and adopted sister or vice-versa? . About 10 other girls, including never aging loli cousin, were left behind most popular girl in school got rejected while other ones never confessed .

52 episodes in 2 seasons.
Next 2 seasons involve same cousin and grandchildren of main characters from 1st series. There's some more incest brewing. But ending isn't a romance one.
5th season involves grandchildren my assumption, most last names don't match anymore, but one can assume so from the ending from 2nd series it's a 100+ year story; what can I say? . Sadly it took ecchi turn and I didn't quite like it.
There's a cat that turns into a human maid with udders.
Robot girl whose fuel is bananamin vitamin in bananas .
Girl that can read people's minds.
And well... other things.
its not about whether you win or loose...
just remember back in early development beowolf was a time traveling monster hunter.
they changed it mostly because he never got funded for a story, (and it was dumb)
No microphone stand joke.
This could have been so funny, here is how I imagined it.
Girl is playing guitar and singing into waist lever microphone while sitting on bed.
Dude comes up, drops towel.
Girl removes microphone puts stand in front of dude.
The Idea made me snicker, that is all.
