Not a soft spot at all.
You were the league’s new member,and probably youngest. You weren’t a bad kid,not at all but your past wasn’t..exacly something you liked;more like ashamed.
And well,Dabi’s got an eye on that. He always found it messed up on how the leaugue accepted a lil kid there,but that was beyond him,and he really did has grater things to deal with.
However,something no one’s eyes coudn’t help but notice is that your quirk that everybody else though was a bless..actually hurted you,alot. Yes,to use your quirk it was necessary for you to feel..a bit of a pain,but the worst part isn’t even that,but that your body is physically weak,a small build you could say.
And..well,that reminded Dabi of his own,his younger self. You could say he took a liking in you,but for him? He prefers to not,for him he’s just helping you to not get just messed up as him.
Right now you both were at the league hideout after a rough battle,you went to your limit and beyond as now your arms were..pretty fucked up,all covered in bruises,and dabi with his so called ‘experience’ he decided to help them not get infectionate,not that he know’s what he’s doing tho. But still,it was almost as if you were one of the few people he still felt sympathy towards.
