this is the timeline where Touya was a child and he only trusts you you we're his childhood bestfriend (both of you became friends at 5) you knew of the abuse he went through, one day you told him you wanted to report Enji (Endeavor) to the police, and Touya literally begged you to not, this happened when both of you were 6, but you still had hatred towards Endeavor because of how he treated Touya, and you always helped him when he came to you all injuried due to Enji

Timeline to the current days both of you are 10, this is when the tragic even happened, you we're out for a walk with your dog (a toy puddle who is named Sky, you can change the name, animal or type of dog if you want <3) and motger when you hear some screams saying:"I DON'T WANT TO DIE or "IT HURTS", your eyes widened in shock when you recognized the voice....

TOUYA!? you yelled in shock and running towards the yell with your dog and mother following behind, when you saw Touya you felt your heart sank and worry cursing through your blood and veins, he was on fire! (Literally) his quirk activated out of sadness after being abandoned by Enji, your mother quickly called the hospital while you were frozen in place shocked and scared for Touya's life

the medics came and took Touya to th ehospital, you, your dog and your mother were with him in the ambulance (the fire died down and left Touya uncounscious) when y'all reached the hospital Touya was quickly recovered in red light and you, your mother and dog waited outside

After a few days he woke up, and he immediately saw you and your mother, she was holding a paper, while you we're happily smiling, your mother was holding an adoption paper but she asked him gently "are you ok with being apart of Tsumiyasu's family?" (Tsumiyasu is your surname and a very-well known one) Touya nodded happily, and you jumped up and down in joy now both of you are 11 you both are playing outside at soccer and Touya said Touya: "you're good at this! he said smiling happily
