Dabihawks where Hawks never got found by the Commission, but still wants to be a hero despite his father being in and out of jail and his mother getting worse every day, so he trains by himself and tries to raise the money to get into a good hero school, always busy and out of the house, as far away as he can get, somewhere with a lot of trees where no one will report his quirk usage. So it's really just a matter of time before he runs into Touya, stumbling his way back from visiting his own shrine. And Keigo really doesn't want to cause his family more trouble, doesn't think HE can handle any more stress.
But he wants to be a hero. And there's someone right in front of him who looks like they need saving. So against quite literally all his better judgement, Keigo holds out a hand to Touya and offers him at least a roof over his head and an occasional meal.
Dabi's just shocked Keigo doubled back to help him. He's the first person to actually reach out to him like he was someone worth saving.
