2. Setting: Cat cafe AU
Possible relationships: TodoDeku, hints of Shinsou x Deku (?)
Izuku is quirkless but even though he couldn't become a hero he at least decided to somehow help others and make them more happy. He opened a cat face, picking up abandoned stray cats, taking care of them and if possible, finding them a new home.
The one who adviced him to do this was his only friend, Shinsou Hitoshi, who helped him to open his own cat cafe.
Izuku just didn't expect heroes finding his little heaven of cats and visiting it almost every day.
(Little info: Cats are an ideal emotional support animal and help ease the symptoms of Post-Traumatic Stress Disorder, depression and other anxiety-related conditions. With quiet affection, their deep attachment to people has been a successful treatment for both physical and psychological health. )
Bonus: * Todoroki is allergic to cat - doesn't stop (nor helps) him from courting Izuku
* Izuku has a cat that strongly resembles Todoroki
* "coincidentally" the cat's name is Sho-chan/Shou-chan
* All Might has his own personally favourite kitten – who for some reason hates his hero form (it's a really smoll kitten – the youngest in Izuku's cafe)
