Pls pls

I forgot if its a manhwa/manga.. the plot is each male generation of two families have to married I think for at least one day??? But after that they can married to a woman or someone else. reason for that is because in the past there was a lover that can't be together because ( I think) their family won't approve them then calamity happened to both families so to dodge calamity each male generation have to get married. the mc and ml's dad are rival (this one I'm not really sure). And I'm pretty sure1 mc and ml is not doing the deed so the calamity happen to them
