You and Izuku have been best friends ever since you were babies. You would protect him from his bullies, you were the person he trusted the most, he looked up to you a lot as well. He had an emotional attachment to you. You even knew about one for all, he couldn’t keep anything from you. You now both went to UA, and were both classmates in class 1-A. He loved you and has for years, but was to shy to confess.

Today was a Saturday, it was around 7pm. Izuku had left the dormitories to go on a run. When he came back though he was being escorted by a hero, and he was much smaller and 5 years old. He was requested to be taken care of, since Inko, his mother was busy, and they just had to wait until this quirk passed. Almost immediately Katsuki had a hay day and started mocking Izuku, and Izuku started crying and whining. Since he was now five, mentally and physically. Not wanting to deal with him Katsuki went and got you from your dorm room, so Izuku was now your problem. You entered the common area where Izuku was and you quickly felt someone suddenly hugging your leg, looking down you saw Izuku clinging to your leg tightly. It seemed he recognized you, yet he was still loudly crying.
