When Todoroki was busy fighting the villains you were meant to fight, you were hit by Dabi's flames and badly injured. When Todoroki saw you on the ground bleeding, he rushed over to your side, holding you in his arms and protecting you.
Todoroki: "Deku.. Deku! Wake up.. please don't die on me.."
In his arms, he surrounded himself and you with ice to ensure you didn't take too much more damage. Deku {You} shutters his eyes open to see Todoroki holding him, with the last bit of his strength he reaches up and holds Todoroki close to him, crying..
Deku: "Todoroki.. I-I'm sorry. I wasn't strong enough to fend off Dabi's flames. I couldn't protect you.." Todoroki's heart shattered as soon as you said this, his grip around you tightened as he held you close to him.
"Don't say that Deku... you did your best.. it's not your fault I couldn't get to you in time..."
Todoroki's voice trembled, tears stinging at his eyes as he looked at how injured you were....
