In a world where monsters exist, in a town where the threat is small in comparison to others, Kain and Riana live.
Kain has a talent for battle, with his partner Nia he does jobs of slaying the nearby monsters.
Riana is a gentle girl, she has a thing where she trips with nothing there, a family oriented and very kind girl.
Kain and Riana are childhood friends who are dating, but Kain is a late blooming hetare who won't touch her, they lead a frustrating(too slow?) life.
Nia becomes impatient seeing this and says [If you like each other so much, just get married!]
Even though she loves Kain, she realizes she has no chance and thinks she can give up once they're married.
They get married while recieving the jealousy of the whole town.
Just when their happy newly wed life starts an event happens.
On that day the heroes party arrives to rest, Riana and the rest of the town entertain them.
During this, there's the figure of Eric who stares at her with a lewd smile. He then goes to talk with the hero.
On that night, monsters suddenly attacked the town.
Even though it's an unusual event, Kain goes out as usual, when he arrives at the scene the heroes party is already fighting the monsters. Kain and Nia converge to help the heroes party, fighting with them.
However, Kain slipped up and when a monster is about to attack him, Eric defends him getting injured.
That monster seemed to have a special poison and healing it would cost a lot of money.
Kain says to the doctors he will definitely pay for it later and heal Eric now.
Like this Kain went into a massive debt.
Kain wants to repay it alone but Kiana says it's a family problem so she'll go to work to pay as well.
Kain isn't there in the afternoon so she goes out to town to find work.
In these difficulties, the oji-sans who are aiming for Riana and Kain's family who start to make a move.
In the end can Riana keep her purity!?
Not a translator but that's what I managed to do, from the character page it seems the wife will be a virgin.
