I know this is a really common post but i just need things to watch and cant find anything online.

Im looking for anime with a fair share of both the action and romance.

For romance I would prefer it be between 2 main characters so not a harem, its alright if they get together at the end but if possible it shows the problems in there relationship. If it could have more of a mature feel thatd be great but it doesnt have to, something like spice and wolf.

I Definitely dont want a weak mc, the female mc can be strong to, even stronger than the mc, but he has to be able to hold his own. I dont mind if the mc is weak at first and gets stronger as the series goes but if he can be strong from the start that'd be great. Also if he has some kinda dark past or is hiding his abilities, especially if he gets underestimated alot but whoops ass. (classroom of the elite, forgot the mc's name but a mc like that would be cool too)

Please if possible its a newer anime, or jus not the typical 90's kinda art, i dont like mecha but if its something like hundred then i dont mind, just no phat machines.

Please have a small summary

Also if possible completed or near completion.

oh and a happy ending, plz i dont wanna cry (but if its really gud i dont mind a sad ending)
