No one expected it, no one. Not deku or anyone. After one year of Ua high school, Katsuki had disappeared for 4 years, and when he reappeared. He was a villain known as Dynamite

After overhearing the 'talk' All might had with deku that year and then Going to UA to be seen as a villan even though he just wanted to be the best. He decided to give everyone what they wanted.

Izuku midoriya hadn't received one for all he. Instead, he was scouted out by a modeling agency and appeared as the model 'Deku'

Katsuki has always loved deku, and the only reason he used to bully deku was because he always felt delu was ahead of him (and to hide his feelings)

One day, deku (21) was coming home from a shot, only to find Katsuki on his couch
