Read here on AO3!
I love you so much I wanna punch you in the face :) (x)
Gonna go ahead and dedicate this to @sangihunweek2026 at the belated last minute, because gdi, I will seal the gaping holes in this ship shut with my own desperate claws if I must.
Already wrote a ridiculous piece for anybody interested in Sangwoo suffering his usual helpless gay feelings.
My contribution to Sangihun Week 2026. Gotta be honest, I really didn't prepare for this as much as I could've. A very grip my brain through squeezing fingers experience that took an entire week to get out, but still had a fun time as I always do with these two, so hope anyone who runs across this may also have a fun time with it. As my writing tends to lean, there's a lot of their usual messy bickering & questionably-timed sex, and Sang-woo lamenting himself & his feelings for his bestie.
Ah, the fic itself would be nice too, yes??? This was inspired by day two [miscommunication] & day three [phone] of the event, by the way.
Can read A Dick on Top of Everything Else here on ao3.
!! MAJOR KARMA SPOILERS [A SHOW WHICH HINGES ON NOT BEING SPOILED] IF YOU WATCH THIS VIDEO !!
Okay so bear with me here, me bringing my partner and I's vast, private universe of Beom-jun (Karma) x Sang-woo (Squid Game) twin brother AU to the public eye, but because it's what I've been insane about the past however-long-Karma's-been-out, I had to share this for shits & giggles. Unsure if anybody but us would get anything out of this hahah. Maybe you @omelettes-s, who I have some vague memory of enjoying several versions of Sang-woo and/or Park Hae-soo's various roles interacting? [Please do not feel obligated to interact, btw, I operate mindlessly sometimes.]
In this iteration of a wide-branching AU universe, BJ and Sang-woo still live out their separate canon story plots, outside of the endings. They're twins, so they do grow up together in Ssangmun-dong, then go their separate ways probably around teen or young-adulthood, when Sang-woo goes off to college and BJ to indulge in his life's many schemes. BJ calls Sang-woo his hyung rather than the other way around just because Sang-woo was born a few minutes before him.
BJ is ironically the one more attached to Sang-woo than it is the other way around, and often tries to reach out to him to catch up, meet up, etc., but Sang-woo always dodges him because BJ has a consistent history of making his life a living hell [will spare the details of this hell].
After yet another dodge, they both get into the terrible parts of their lives. Sang-woo with the games. BJ with the job that goes horribly awry for him. But instead of their canon endings, Sang-woo survives the games, absolutely wrecked, lost Gi-hun, and on the verge of suicide ofc, and BJ also survives enough to try and give Sang-woo another last-ditch call. This time, Sang-woo actually picks up.
I like to imagine they reunite after this, the two of them ending up back home trying to recover from varying degrees of extreme trauma, reluctantly forming some semblance of a bond after the decades apart.
This video was really a ridiculous quickie/snippet I came up with as to how this would all likely [and vaguely] take place. Somewhere down the line we hc'ed that BJ would be into the band Interpol [I can't entirely remember the why of that.... @faded-smiles, you remember?], so that's why the song is what it is. But man, we've got a MASSIVE world for these two, even worlds that include more brothers. Mainly triplets, but there's been quadruplets in the brain at some points. A family of Park Hae-soo characters is really what we've done, lmao. We're known to include the Squid folks too, like Gi-hun and In-ho... have even pulled from shows like Nice to Not Meet You ahahah. Like said, many iterations.
Still tend to hc that Sang-woo is in love with Gi-hun in most of them. The characters still have their personalities from the show they're originally from, though Beom-jun may have slightly more "emotion" than portrayed in his, solely reserved for Sang-woo (and sometimes his other siblings). Twin bond & all.
It's an absurd day and hour to do so, but I've found this hasn't ever stopped me. I've got chapter 10 of The Temperature's Rising (It Isn't Surprising) now up and posted, for all interested. In-ho's back in the fray [oh is he ever...], the story's reached a fairly unhinged climax, and oh yeah, did everybody see the fanart kwidawpirmi envisioned of the smut that took place last chapter??! BAAHHHH, the love this story has received since its start I'm regularly blown away & thankful for 🙏
Oooh, thank you for the dirty ask, anon! >:3 I realize you asked for HCs, but this took on a life of its own and became a silly short story. I hope you enjoy! Full answer is below the cut.
If Sang-woo was a porn star, I imagine it happening out of desperation. Picture him losing his job at the bank and falling on hard times. Maybe he was doing some illegal investments with his clients' money, like in canon, so he's unable to get another job at a different bank.
One night he's drunk. He winds up posting a video of himself masturbating. I always HC Sang-woo being well-endowed down there, so he gets a lot of attention!
One thing leads to another, and evil In-ho stumbles upon the video. He uses his sus skills to find Sang-woo. Creepily enough, he winds up at his apartment. He advises that they have a chat and takes him out to eat.
In-ho tells him how he's seen his video and how he could have a real future in making content like that full time. He informs Sang-woo that his big dick is an asset, much to Sang-woo's pride and embarrassment. Seeing as he's about to be evicted from his apartment, he has no other choice to agree.
Since Sang-woo is older than In-ho, In-ho proposes his porn name is Well Hyung. Sang-woo rolls his eyes but agrees.
It starts out small with Sang-woo making more masturbation videos, though it starts to escalate over time. Eventually, In-ho makes a series of videos featuring Sang-woo fucking the Recruiter.
The problem? Sang-woo's a bottom, but he has Big Dick Energy.
It's tough making money in South Korea with the strict laws surrounding the adult entertainment industry, so In-ho gets Sang-woo to move to Los Angeles with him, isolating him further.
Eventually, he wants to leave but doesn't know how. One day, Gi-hun stumbles upon one of the videos. He makes it his mission to save Sang-woo! It's almost impossible since Sang-woo never answers his phone, so he has a hell of a time finding him.
Then Gi-hun bumps into Sang-woo one day when he's visiting Ga-yeong in LA. He runs into him in Koreatown. Gi-hun demands to know what the hell is going on. He says how he's seen the videos and Sang-woo is too smart for all of this.
Sang-woo says how being smart doesn't always pay the bills, but Gi-hun can see the shame in his eyes. Gi-hun tells him he's coming home with him. He and Jung-bae need an egghead to do the books for their chicken shop. Sang-woo agrees with a quiet nod.
In-ho tries to stop them, but he's a simp for Gi-hun. He tells Gi-hun he will rip up his contract if Gi-hun "performs fellatio" on him for 45.6 billion won. Gi-hun's baffled but has to agree for THAT kind of money.
Once the deed is done, he tells Sang-woo they're free. He helps Jung-bae with their debts regarding the chicken shop. Then he and Sang-woo run away together to Jeju Island, to live out the rest of their days peacefully. The only porn they make is now in the privacy of their own home. :)
