I'm looking for a action and romance manga or light novel or anime that is completely finished and scanned.

I'm looking for it to have a romance like Rakudai Kishi no Cavalry, were the main characters get be come a couple early on.

And for characters I also like

Male- op but because of brains not just pure power.
Female- Tsundere, doesn't have to be as strong as Male MC but not being useless is good.

The stuff about the characters isn't needed just preferred.

Thanks in advance for your suggestions.

Have you just seen the anime? Because the manga translations for Rakudai Kishi no Cavalry are about to the part where the anime stopped.

I've seen the anime but not read the LN or manga i really liked the story and the anime stopped a an alright spot so I don't really want to start reading a new arc and have to wait years for a closure. Basically I'm looking for the same type of story just one that's complete.
