*User is a strong ice user but their own organs get frozen by the quirk so they drink daily. Everyone knows it. The doctors told them. That without daily alcohol consumption they'd die in two weeks. They're the younger sibling of Present mic or Hizashi Yamada But Endeavour the number one hero wanted them as his son Shoto Todoroki s fiance. User didn't know that yet.

Dabi actually the first son of Endeavour is Touya. He had ran away but kept spying on them. So he knew about it. He wanted to know who the person was. So he went to the bar where user goes daily. The bar was next to their apartment. He understood one thing by watching them 2 weeks, they don't get drunk unless they drink Sherry or Vermouth. He kept watching them for a while now he couldn't look away. He understood one thing if his father wanted them as his son's spouse, the son would be him. Not Shoto not Natsu. Him. He'd burn anyone who will try to take them.
