Won't say I'm in love

All mights son

When Izuku Midoriya found out that he was quirkless he felt all his dreams shatter. He would never get to be a hero like his dad and so he just cried. He cried for hours not even remembering leaving the doctor's office, he just remembers the feeling of helplessness as he desperately wonders how he's going to be a hero now.

At some point he hears the familiar call of, " I am here" and looks up to see his dad towering above him and the tears just stream down his face uncontrollably,

     "Dad, can I be a hero even if I don't have a quirk?"

Toshinori just stares down at his son and then crouches next to him and gives hi a big hug, " Without a quirk it would be almost impossible but what if I told you there's a way to pass down my quirk to you"

    Izuku just stared up confused and his father smiled at him, "son its time I tell you the story about two brothers and their quirks one for all and all for one-"

Midoriya could never tell anyone that his Dad was All Might for fear of what both the media and villains would do with that information.

    "COME BACK HERE YOU USELESS DEKU!!!!" Izuku could hear the explosion already popping off behind him as he ran home that day. Izuku had informed anyone who asked that his family had a history of developing quirks late but most took that as a sad delusion of a kid who just didn't want to accept his life.

Combine his apparent lack of a father, quirklessness , and weird hero mumbling he was constantly bullied. Izuku didn't want to worry his parents so whenever asked he would just shrug all concerns off

    "Is that a burn mark!?!?!"

    "Don't worry mom me and Kacchan were just roughhousing you know how he can be"

    She would alway look sad and Izuku suspected she might have suspicions that things weren't that simple but he couldn't bear to tell her the truth. She knew just as well as him that they lived in a quirkist  society where those with quirks that are deemed useless or villainous  are ostracized and those unlucky few who are quirkless find it almost impossible to live due to discrimination.

His dad however was completely oblivious to a lot of the bad parts of the world for being a number one hero. If Izuku told a story about what he and kacchan got into that day Toshinori would just nod and smile,

    "I'm glad you had such a fun day with your friend, my boy. It's important to have these friendships."

But for the most part Izuku couldn't complain about his life. He may be quirkless now but he knew he wouldn't be forever. He may not have a lot of friends but both his parents loved him and gladly supported his dreams.

Now that Izuku was in his last year of middle school his dad had finally decided it was time to pass down his quirk. They had been training his body for years so that he would be ready for it. Even though he was super excited to be receiving a quirk he was also worried about his dad ever since his big fight with all for one he had been getting weaker but with passing on his quirk it wouldn't be too long before he had to stop hero work altogether.

    When Izuku expressed his worries all might just laughed them off,  "no need to worry my boy because I am here even when I can no longer be a hero, now eat this lock of my hair"

     "WHAT?!?!?"

    "Yes, tol inherit my power you must ingest something with my DNA, surely I have mentioned this already."

     Izuku's dad waved the golden hair in his face until he snatched it away and ate it.

    "I don't feel any different"
   
    "Well why don't we go down to the beach and try it out"
