I see your childhood friend, hyper-codependent Dabi agenda with that dash of pro hero - villain angst, and I fully agree, but may I raise:
Villain Dabi and Outlaw! Reader
(TW for canon typical violence, yandere-esque derangedness ig??, depiction of unhealthy relationships and explicit content )
Young Touya, who got befriended by the kid from across the street behind his father's back. His childhood was all training to live up to his father's expectations, but this little rebellion (with his mother's help) was *his* and his alone.
Young Touya, who from one day to another didn't see his friend anymore. It took months for Young Reader to show up at his window again. He learns that Reader's parents gave up their guardianship to the grandparents, because Reader got a quirk that their parents refused to be associated with (saying it was a quirk of a villain). It took a while but they managed to come all the way back to him.
Young Touya, who sneaks Reader into his room, just so he could spend time with his only friend.
Reader, who believing that Touya really died, loses their faith in society and the heroes completely. Touya, who desperately tried, and ultimately failed, to find his friend after faking his death.
Dabi, the notorious LOV member, who doesn't believe his eyes when he spots Reader in a dark alley beating up a mugger, before disappearing among the shadows. And once again, when Reader resists arrest at the hands of a rookie hero and makes a bit more dramatic escape.
Dabi, who can feel his heart turning to ash when Reader doesn't recognise him, nor do they believe him when he tells them that it's really him. It breaks a bit further when he sees how the light had left Reader's eyes completely.
Dabi, who tries to get Reader to join the LOV, but they're only willing to help if the mission directly targets Endeavor, otherwise they're following their own moral code.
Dabi, who has to keep the nonchalant facade up when around the rest of the LOV or fighting heroes, but every day gets closer to a breakdown. He just wants his friend back. He's willing to drop to his knees and beg. He's willing to do anything.
Dabi, who finds Reader injured and unconcious. When Reader wakes up to the sight of a borderline panicing Dabi, gets a flashback from their childhood. The two of them snuck out at night, and Reader fell - it was barely a scratch, but Touya freaked out like it was a fatal wound. That borderline comical expression is what makes them recognise him. He cries whe Reader calls him Touya again.
Dabi, who brings Reader over to the LOV's hideout constantly. The rest of the League is antsy, not only because an outsider knows where they are located, but because how effortlessly they wrapped Dabi around their fingers. Reader has no idea about Dabi's deranged obsession. They only see their old friend: socially hopeless and clueless but way too genuine and excited to be left alone.
Dabi, who shoves his face into the jacket or hoodie that Reader forgot in his room whenever he's alone for the night, one hand keeping the fabric in place, the other down his pants. If the cloth is well-worn and sweaty he simply finishes faster and goes for another round. He's addicted.
Dabi, who upon seeing Reader fight Endeavor and go for his throat, enters something that's uncomfortably close to a religious psychosis. There's no going back for him. (If there ever was to begin with)
Dabi, who drags Reader far, far away from everyone after the fight into a secluded alley and shows his tongue down their throat. He's a whimpering mess when he feels Reader kiss back. He comes in his pants when Reader yanks him closer by his belt.
Reader, who starts to show up at the hideout on their own accord more often, rather then waiting for Dabi to invite them over. They start to realise that they have power over him, but still underestimate it by miles. The others see it clearly, and they don't like it at all.
Dabi, who tells Reader about his plan for revenge against his brother and father. Reader still remembers clearly Endeavor's tyranny over the whole family - Shoto included, and is NOT happy with Dabi about it. Que their first arguement, if it even can be called as such. Dabi was folding and apologising two sentences in. He didn't even know what he was apologising for. He just knew that he wasn't taking revenge on Shoto.
Dabi, who either has to lay on top of Reader when cuddling or has to have them lay on top of him - even when sleeping. Anything less than that and he's fighting hyperventillation. When the two fall asleep with Dabi on top there's a fat chance that Reader will wake up to Dabi humping them in his sleep. Even though they're strong, they can't lift his whole dead weight off themself. They can only hope that the friction is enough to get them off before it gets Dabi off, or else they will be left turned on with Dabi peacefully sleeping on top of them, without leaving them any way to help themself.
Reader, after one too many incidents like that, decides to let the frustration out. Except no matter what they do, Dabi enjoys it - wether it's hours of edging or driving him crazy with overstimulation, he's down for it without complaint. And honestly, how could he complain? Why would he complain? His one and only's attention is on him. They could spit in his face and he would thank them before asking for another one into his mouth.
Reader, who all but has to sneak out of the hideout if they want to do anything without Dabi coming along, let it be getting supplies or fighting criminals who aren't fit into their ideals and morals. Even though they're growing to strongly love him, he can be too much at times. Dabi, who freaks out every. Single. Time. When he wakes up alone.
Dabi, who burns every single villain, low-life, cop or hero to cinders the moment they attempt to fight Reader.
Reader, who spends most waking moments with figuring out how to cause the downfall of Endeavor. It's still personal.
Reader and Dabi, who are all but unstopable when fighting together, protecting each other's back.
So, yeah. Strongly codependent Dabi with hyper independent Reader. I hope you know you caused this brainworm and you enjoyed the food.
