CW: angst, selfharm, abusive relationships Soulmate AU where people...

Soulmate AU where people get soulmarks in their 18 birthdays and some counterculture develops in some very dark punk scenes where teens get their marks burnt /cut the moment they appear by a friend so they never have to see it.
So right at midnight, when
And then another teen, in similar situations, find out what they did and beg them for help.
At first it's just a friend helping the other out. And then two friends. And then someone from another town over hears about it.
And so it goes.
All marks being erased.
Or so they think.
Because what teens don't realize is that they won't be 18 forever. They don't realize scars are only skin-deep.
They don't realize the marks they got rid of aren't called skin marks for a damn good reason.
You can't burn away your soul.
Maybe Katsuki is the one who burns his mark. He saw how destroyed his mother was when Madara cheated on her, how she became bitter and mean in a way she wasn't before. He knows how much like her he is and he refuses to let that happen to
But then almost a decade later he meets a guy with the brightest smile he ever saw and they just have this instante connection he can't explain. They go out, start dating, start falling in love... But it comes the time when he sees Katsuki's scar where the mark should be
You see, Izuku is a romantic and he **loves** his soulmark. It's a beautiful orange explosion with the kanji for victory in the middle. Since the moment he got the mark, he fell in love with the person who it represented. Whenever life got hard,
Izuku dreamed about seeing what the mark of his soulmate would be. Is it beautiful? Is his soulmate proud of bearing it?
He'll never be sure if the guy who he feels so strongly about is really his soulmate... And if he is, Izuku will never know if the mark he left on Kacchan's skin was pretty, if it was something to be proud of...
His mom's soulmate left her the moment he found one she was pregnant. Izuku grew up seeing the painful loneliness of his mother, seeing how hard the world treats single moms, seeing how much she struggled on her own...
So he cuts it off. It's not going to make any difference in his life anyway.
What he doesn't know is that just a few blocks away, that night, as Izuku makes his skin bleed,Katsuki gently caresses the green lightning on his shoulder, excited to talk to Deku
