Looking for completed manga or light novel that has a romance element

[Strike105X]

Hi i'm looking for manga that has a romance element, preferably something that ends at least a bit conclusive, but i don't really want slice of life, i want it with some fantasy or action or sci fi, anything works:

Here are some examples of what i read and liked:

Rosario+Vampire
Superior 
sun ken rock

 

The main thing i do want though is for it to be completed. No ongoing, i'm already at my wits end with Toaru and The legend of legendary heroes.

There's Kara no Kyoukai which is part of the nasuverse, the manga is still ongoing but the light novel is complete and fully translated (by fans), if you want  to I can share some links.

Try Busou Renkin

While there are mild slice of life elements I have to recommend the Mushoku Tensei web novels. They have been fully translated to English and it's 24 volumes long. This series has it all action, adventure, romance, fantasy, drama, and comedy.
