Hello there, fellow KaiSooists. I have never had as much concentrated written fun as when I was reading these fics. I really love intense violence/crime AUs and I had to leave out so many spy and hitman and military fics for the sake of sticking to mafia. SO I REALLY HOPE YOU ENJOY LIKE I DEFINETELY DID.
Mafia Boss - kyungsoo is the mafia mob leader / vampire and has his secretary jongin by his side. he has to protect jongin since they got an unexpected news from him (mpreg)
Mad Love - mafia au, jongin is kinda soo's trophy wife ;) lots of sexual tension, nini in stockings n purple cropped sweater uwu
Bluff - ot12, unfinished but chaptered. My all-time full EXO favourite. In a mafia based on playing cards system, Kai is a Heart and Kyungsoo the “leader” of Spades. Jongin betrays his group to join Kyung. Tao-centric but godDAMMIT THIS AUTHOR PREDICTED LOVE SHOT AND LEFT US ALL HANGING. I adore this, I really do.
Not Good People - Kyungsoo only wanted to prove his independence to himself and to his mafia boss of a brother, but he wasn't going to complain when he got unexpected sex ed from a hot gang leader.
Ascending Rain - Yakuza!AU, psychological, angst(?), mystery, smut. You know what's hot? Japanese mafia heir tatted up Jongin and pristine looking genius sociopath Kyungsoo. You know what's even hotter? Both of them being in the darkest love-hate relationship in between murders and mind games. So much plot, so many details, great OCs, and occasional first person chapters. Awesome read, too bad it's unfinished.
spring snow - Character death, multiple ships. This is practically the modern shorter version of 48 Hours.Yixing helps Jongin find the man he left behind and watches a mafia slowly die out. It's heartbreakingly good.
Running Up That Hill - Recced before, but I can’t not mention this legend. A chaptered masterpiece with suspenseful angst, awesome smut, intricate detailed plot, ot12 characters, side XiuHan, top!soo and violence. No matter what I do there is no way I can express how unbelievably addicting this fic is. Just read it, it should be a fandom classic by now.
smoke - Oneshot. Kyungsoo as the heir to a security firm discovers that his dad is caught in mafia business. Later, as a president, he is faced with the same pressure from Kim Kai, the heavy smoker mob leader himself..
safe like springtime - only two chapters so far, with Jongin being bratty son-of-a-mobster teenager!Kyungsoo’s confused bodyguard.
4x4 (and away we go) - Twoshot, smut, tw. The Kim family is indepted to the famous stoic mafia leader, Do Kyungsoo, and Jongin finds himself obliged to pay back. Uhm, unsettling
Subterfuge - Oneshot, smoking. Kyungsoo’s a mafia leader, and Jongin a heavy smoker barman. Again, a subtle piece that leaves you wanting more. (a.k.a I’m really whipped for kaisoo and mafia!au)
bang and burn - Incomplete, 4 chapters, pretty heavy drug use, smut and very mild angst. Jongin doesn’t understand what his retired sniper ex did to be worth a million dollars, but dead. He also didn’t understand how in ten years, his pancakes and skin are just as delicious. Indigo’s (a.k.a my favourite active author) freaky shot at assassins. Pretty damn awesome.
in their blood and from the gutter - Oneshot, angst, smut, side BaekXing and murders. Kyungsoo is an associate of the biggest mafia ruling the city. He’s constantly in danger but one assignment officially makes him a dead man. An intense great read ; I’m not a fan of open endings but holy damn, I loved it.
and your sexy enemies closer - SeKaiSoo, based on the Love Shot MV, with bits of crack and uhm, a weird fingering scene. It was pretty good and unsettling because my first KaiSoo+someone fic.
I really don’t wanna let this rec go, but here, the latest pure mafia!AU rec. You can also (re)check other awesome fics here for extra action. And, well, long live KaiSoo, with lots of guns and rainbows.
