I had read this exo fanfic a few years ago and it's been bothering me for a long time because I want to find it.
I forgot the name but it's a sehun fanfiction, where an oc is married to sehun. But sehun is not loyal he cheats on her by having sex with other women for his enjoyment. She got used to it I remember this one part where he just got done having sex with a random girl and she came in to go to the nightstand and glared at the random girl scaring her a little.
Then she thought about how he was never like this it started after their marriage. And how she is like the ceiling of a company or something.
Then baekhyun is having the same trouble, but with his wife, an oc he is also used to it. And she promises she will change she loves him, but he caught a condom and he was done. But he become friends with sehuns wife and takes a liking to her, his wife doesn't like that so she starts to flirt with sehun at a lunch date but gets nothing because sehun bring luhan along.
And I remember his wife is not aloud to go to any of his concerts, and kai heard about it and never knew sehun had a wife with how flirtatious he is with his fans.
I remember one part of the smut with sehun and his wife where he smells her buds (part of her vaginas I think) and the smell like velvet (it's kinda weird when I write it down) and how she waxed herself and then baek is getting slide to his wife and he doesn't like it i think.
Also I think sehuns wife is named jieun
